Worm Gear Motor FAQ
Common selection questions for matched worm gearbox and motor assemblies.
What is a worm gear motor?
A worm gear motor combines an electric motor with a right-angle worm gearbox to reduce output speed and increase available output torque in a compact drive assembly.
What is a worm gear reducer motor or worm gearbox motor?
Both terms describe a matched electric motor and worm reducer drive. The suitable configuration depends on your output speed, torque, duty, mounting and electrical supply.
What information is needed to select a worm drive gearbox with motor?
Please provide required output speed and torque, motor voltage and frequency, operating hours, starts per hour, mounting position, shaft or flange arrangement, application and quantity.
Can the motor and gearbox be ordered separately?
Yes, depending on the required configuration. SMK can supply a matched assembly or help confirm compatible motor-flange, input and output dimensions for separately ordered components.
