Some OEM models are available with non-standard timing/torque. The torque rating for dual-ended shaft motors is the sum of the shaft torques (power-end torque plus auxiliary-end torque). Breakaway torque is maximum torque available to overcome occasional large loads such as a seized damper or valve. - Page 6 SERIES 90 MODUTROL IV™ MOTORS Adapter Bracket The 220738A Adapter Bracket, positioned between the motor and the equipment, raises motor shaft height by 0.75 in.
