Design Tips:

Series connect lead wires for best torque at low speeds.
Center tap to end or parallel connect lead wires for best torque at higher speeds.
Keep motor case temperature below 100° C. This can be achieved by lowering the motor current or limiting the duty cycle.
Allow sufficient time to accelerate load.
Size motor with 100% safety factor for required torque @ speed.
Do not disassemble motors. A significant reduction in motor performance will result.
Do not machine shafts without consulting TOPS.
Do not disconnect motor from drive while in operation.
Do not use holding torque/detent torque of motor as fail safe brake.

Motion Installation Tips:

Mount the motor securely against a surface with good thermal conductivity such as steel or aluminum.
Properly align the motor with the load using a flexible coupling.
Protect the motor shaft from excessive thrust, overhung and shock loads.
