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.
