5.17 DC Motor
This is a 3V DC motor. When you give a high level and a low level to each of the 2 terminals, it will rotate.
• Length: 25mm
• Diameter: 21mm
• Shaft Diameter: 2mm
• Shaft Length: 8mm
• Voltage: 3-6V
• Current: 0.35-0.4A
• Speed at 3V: 19000 RPM (Rotations Per Minute)
• Weight: Approximately 14g (for one unit)
Direct current (DC) motor is a continuous actuator that converts electrical energy into mechanical energy. DC motors
make rotary pumps, fans, compressors, impellers, and other devices work by producing continuous angular rotation.
A DC motor consists of two parts, the fixed part of the motor called the stator and the internal part of the motor called
the rotor (or armature of a DC motor) that rotates to produce motion. The key to generating motion is to position
the armature within the magnetic field of the permanent magnet (whose field extends from the north pole to the south
pole). The interaction of the magnetic field and the moving charged particles (the current-carrying wire generates the
magnetic field) produces the torque that rotates the armature.
