Gearbox Selection Guide
Gearbox FAQ
What is the main function of a gearbox?
A gearbox changes the speed and torque delivered by a motor to match the requirements of the driven equipment.
What is a gear motor?
A gear motor combines an electric motor and gearbox into an integrated drive unit for controlled speed and torque transmission.
How do I select the right gearbox ratio?
The required ratio is primarily determined by the motor speed and desired output speed, while the required output torque must also be considered.
What is the difference between a gearbox and a gear motor?
A gearbox is the mechanical transmission component, while a gear motor combines a gearbox with an electric motor as an integrated drive solution.
Can a gearbox be integrated with a BLDC motor?
Yes. A gearbox can be combined with a BLDC motor to provide controlled speed, increased output torque, and compact mechanical integration.
What is a spur gearbox?
A spur gearbox uses spur gears to transmit rotational power and provide speed reduction between the input and output shafts.
What information is needed for gearbox selection?
Important information includes input speed, required output speed, torque, gear ratio, installation dimensions, shaft requirements, and operating conditions.
Can gearbox dimensions be customized?
Depending on the design and application requirements, dimensions, mounting configuration, shaft configuration, and other mechanical parameters may be customized.
Can United Motion provide customized gear motor solutions?
Yes. United Motion can support customized gearbox and electric motor integration for application-specific motion systems.
