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 100½ 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 Applied Motion Products.
• 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.
