a
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.
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).
