Table 6. Series 61 and 62 Modutrol IV Motor Timing and Torque Ratings.
NOTE: Torque designation corresponds to torque rating
at standard timing (nominally 60 seconds for
160° and 30 seconds for 90° except for 300 lb-in.
motors that have timings of 2 or 4 minutes).
IMPORTANT
Never use motor continuously at the Breakaway

Timings apply to all TRADELINE models. Some OEM models are available with non-standard timing/torque.
b
Torque ratings for dual-ended shaft motors are the sum of the shaft torques (power-end torque plus auxiliary-end torque).
c
Breakaway torque is the maximum torque available to overcome occasional large loads such as a seized damper or valve.
