The T-Motor AT ESC (Electronic Speed Controller) is designed for fixed-wing aircraft and multi-rotor applications, offering a range of features for safe and reliable flight. This brushless ESC incorporates original and genuine components to ensure high quality and reliability.

Function Description:

The AT ESC manages the power delivery to a brushless motor, controlling its speed and direction based on throttle input from a remote control. It includes multiple protection functions to safeguard the ESC, motor, and aircraft during operation. The ESC can be configured for different flight modes, including fixed-wing and helicopter (linear throttle/external governor), and allows for detailed parameter adjustments. It also provides data logging capabilities and real-time RPM signal output.

Important Technical Specifications:

  • Mode: AT 195A HV
  • Input Voltage: 6~14S LiPo cells
  • Continuous Current: 195A
  • Instantaneous Current: 240A (for 10 seconds)
  • BEC: No (This ESC does not include a Battery Eliminator Circuit, meaning an external BEC is required to power the receiver and servos if using this ESC with a flight controller that doesn't have an integrated BEC.)
  • Maximum Motor Speed:
    • 210,000 RPM (for 2-pole motors)
    • 70,000 RPM (for 6-pole motors)
    • 35,000 RPM (for 12-pole motors)
  • Throttle Range (Default): 1100µs to 1940µs (requires recalibration upon first use or transmitter change)

Programmable Parameters (with Factory Default Parameters):

  1. Flight mode:
    • Value: Fixed wing, Helicopter external governor
    • Default: Fixed wing
    • Explanation:
      • Fixed wing: Suitable for fixed-wing and multi-rotor aircraft. The motor starts when throttle reaches 5% or above, offering quick throttle response.
      • Helicopter (Linear Throttle/External Governor): Applicable to helicopters not using speed-governing devices or those using external governors. In this mode, "response time" becomes "soft start-up enable/disable."
  • If "soft start-up enable" (response time 1-21), motor starts softly and then accelerates to current throttle.
  • If "soft start-up enable" (response time 0), motor responds rapidly to throttle input.

  1. Lipo cells:

    • Value: Auto calculation, 6~14S
    • Default: Auto calculation
    • Explanation: Automatically calculates LiPo cell count based on 3.7V/Cell. Manual setting is recommended for LiFe or LiHV batteries to ensure correct detection.

  2. Voltage cutoff model:

    • Value: Soft cutoff, Hard cutoff
    • Default: Soft cutoff
    • Explanation:
      • Soft Cutoff: Gradually reduces output to 50% of full power when voltage cutoff is activated.
      • Hard Cutoff: Immediately cuts off output when voltage cutoff is activated.

  3. Low voltage protection value:

    • Value: Turn off, 2.8V~3.8V
    • Default: Turn off
    • Explanation: Adjustable per cell voltage. For a 6S LiPo, the final cutoff voltage is the set value multiplied by 6.

  4. Response Time:

    • Value: 0~21
    • Default: 2
    • Explanation: Adjusts throttle response. Higher values result in slower throttle response.

  5. Governor Parameter P:

    • Value: 0~9
    • Default: 4
    • Explanation: Controls ESC compensation for motor speed during speed-governing. Higher values mean greater compensation.

  6. Governor Parameter I:

    • Value: 0~9
    • Default: 5
    • Explanation: Compensates for speed falls or exceeds expected values. Too large a parameter can cause overcompensation; too small can cause undercompensation.

  7. Auto Restart Time:

    • Value: 0s~90s
    • Default: 25s

  8. Restart Acceleration Time:

    • Value: 1s~3s
    • Default: 1s
    • Explanation: Controls the time the motor needs to start from standstill and accelerate to full speed for a rapid restart.

  9. Brake Type:

    • Value: N/A, Normal, Proportional
    • Default: N/A
    • Explanation:
      • Normal Brake: Effective when moving the throttle stick to the bottom position. Controls brake speed. Higher value means more powerful brake force and shorter time to standstill.
      • Proportional Brake: When throttle range is 20% to 100%, output is 0% to 100%. When throttle range is between 0% and 20%, corresponding brake force is between 0% and 100%.

  10. Brake Force:

    • Value: 0~100%
    • Default: 0%

  11. Timing:

    • Value: 0°~30°
    • Default: 18°
    • Explanation: Adjusts ESC timing.

  12. Motor Rotation:

    • Value: CW, CCW
    • Default: CW
    • Explanation: Sets motor rotation direction. Default is CW. Connecting to ESC, if motor rotates clockwise, setting to "CW" will make it rotate counterclockwise. If motor rotates counterclockwise, setting to "CCW" will make it rotate clockwise.

  13. DEO Start up:

    • Value: ON, OFF
    • Default: ON
    • Explanation: With this enabled, throttle linearity will be improved.

  14. Start-up Force:

    • Value: 1~7
    • Default: 7
    • Explanation: Adjusts the start-up force of the motor during the start-up process. Higher values result in larger start-up force.

Usage Features:

  • Throttle Setting Process (Recalibration):

    1. Turn on transmitter, move throttle stick to top.
    2. Connect battery to ESC. Motor emits "123" (ESC powered on).
    3. Motor emits "♪beep-beep" (highest throttle point calibrated).
    4. Move throttle stick to bottom within 5 seconds, wait 1 second (bottom throttle calibrated).
    5. Motor beeps number of short beeps (number of LiPo cells plugged in).
    6. Motor emits long beep (calibration complete, ready to fly).
    • Note: The throttle range is 1100µs to 1940µs by default. Recalibration is required upon first use or when changing transmitters.

  • Normal Start-up Process:

    1. Turn on transmitter, move throttle stick to bottom.
    2. Connect battery to ESC. Motor emits "123" (ESC powered on).
    3. Motor beeps number of short beeps (number of LiPo cells plugged in).
    4. Motor emits long beep (calibration complete, ready to fly).

  • ESC Programming (using AT DATA LINK - purchased separately):

    1. Plug AT DATA LINK wire to ESC port and AT DATA LINK connector. Connect battery to ESC.
    2. Press "√" on program box to connect. Firmware version will display.
    3. Enter Parameters page, press "=" to browse data, press "±" to adjust values.
    4. Press "√" to save new values to ESC.
    5. Disconnect LINK, power cycle ESC to run new parameters.

  • LED Indicator and Warning Tones:

    • The input voltage is abnormal: "BB. BB. BB..." beeps, red LED flashes along with beeps. (Cause: Input voltage out of regulated range).
    • The throttle signal lost: "B. B. B..." beeps, red LED flashes along with beeps. (Cause: ESC doesn't detect any throttle signal input).
    • The throttle stick is not moved to the bottom position: "B. B. B. B..." beeps, red LED flashes along with beeps. (Cause: ESC detects throttle is about 0%).
    • The throttle range is too narrow: "B. B. B. B..." beeps, red LED flashes along with beeps. (Cause: You set the throttle range is too narrow during ESC calibration).
    • The ESC thermal protection is activated: NO beeps, blue LED flashes once and repeat. (Cause: Internal temperature of ESC goes above regulated temperature range).
    • The low-voltage cutoff protection: NO beeps, blue LED flashes twice and repeat. (Cause: Operating voltage goes below the protection cutoff voltage).
    • The over current protection: NO beeps, red LED turns on solid. (Cause: Operating current goes above regulated value).

Maintenance Features:

  • Multiple Protection Functions:

    1. Abnormal Input Voltage Protection: If input voltage is outside the regulated range, the ESC will activate protection, flash red LED, and beep.
    2. Start-up Protection: Monitors motor RPM during start-up. If speed is unstable or stops increasing, it's a start-up failure. If throttle < 15%, ESC retries. If throttle > 20%, move stick to bottom and restart. (Possible causes: poor connection, blocked propellers).
    3. ESC Thermal Protection: Gradually reduces output (up to 50%) if ESC temperature exceeds 110°C (Soft Cutoff mode). Resumes full power when temperature lowers. If powered on, temperature cannot exceed 70°C; otherwise, it won't start and flashes blue LED with beeps. In Hard Cutoff mode, power is immediately cut off.
    4. Throttle Signal Loss Protection: Cuts off output immediately if signal loss exceeds 0.25 seconds to prevent continuous high-speed propeller rotation. Resumes normal output when signals are received.
    5. Overload Protection: Cuts off power/output and automatically restarts if load suddenly increases. If load remains high or motor is out of sync, power/output is completely cut off.
    6. Low-voltage Cutoff Protection: Gradually reduces output (up to 50%) when operating voltage drops below preset cutoff. This allows for safe landing. A fully charged battery is needed to resume operation.
    7. Over-current Protection: Cuts off output immediately if current exceeds regulated value, then quickly resumes. If the regulated value is exceeded again, output is completely cut off and won't resume.

  • Data Logging: Records minimum voltage, maximum temperature, maximum current, and standardized RPM of flight.

  • RPM Signal Output Port: Provides real-time electrical RPM of the motor.

  • LED Indicator: Indicates running status and possible troubles.

For any problems, users are advised to contact their local distributor or T-MOTOR for technical support.
