A gear motor refers to an electric motor with a gearbox. In terms of the gearbox, gear motors can be sorted into gear reduction motor, variable speed gear motor, increasing speed gear motor. Generally speaking, the gear motor refers to the gear reduction motor since it accounts for the majority of gear motors. Thus, a gear reduction motor is a motor coupled with a set of gears to decrease speed and increase torque.
As is known to us, for a single motor, the slower the speed of a motor, the larger the size of the motor. Moreover, a larger motor is more expensive and is not suitable for some compact space applications. Here comes the gear reduction motor. Using a small motor with a gearbox can significantly decrease speed and increase torque, which allows for small space applications.
How Does A Gear Reduction Motor Work?
The gear reduction motor is to use all levels of gear transmission to achieve the purpose of speed reduction. The gearbox of the gear motor is composed of various gear pairs. A small gear can be used to drive a large gear to achieve a certain reduction. This kind of structure can greatly reduce speed. The gear reduction motor is generally used for low-speed and high-torque transmission equipment. The gear with fewer teeth on the input shaft of the gearbox will be meshed with a larger gear on the output shaft to achieve the purpose of deceleration of the high-speed rotating electric motor.
The ratio of the number of teeth of the large and small gears is the gear ratio or reduction ratio.
But for a planetary gear motor, which is the most common one in gear motor, the calculation of reduction ration will be different. Normally, a planetary gearbox has several stages.
For example, if the available reduction ratios for a 1-stage gearbox are 4, 6, the gear ratios for a 2-stage planetary gearbox are multiple of these, (4×4, 4×6, 6×6). The gear ratio for a 3-stage gearbox is the multiple of these gear ratios of three stages.
What are the Characteristics of a Gear Reduction Motor?
- Reduce speed at your will.
- Low energy consumption, superior performance, and the efficiency is as high as 95%.
- Space-saving, reliable &durable, high overload capacity, and the voltage can be customized.
- Precision machiningallows for accurate positioning. The gear reduction motor consists of the gear transmission and various motors, forming a mechanical-electrical integration, which improves the product quality.
- Low vibration, low noise, high energy saving, high-frequency heat treatment on the surface of the gear.
- The gear motoradopts a serialized and modular design concept and has a wide range of adaptability. There are plenty of choices of motor and gearbox combinations for you to choose from.
What are the Application Scenarios of Gear Reduction Motor?
Gear reduction motors are widely used and are indispensable power equipment for mechanical equipment, especially in today’s era of increasing mechanical dependence. Here are some examples of applications:
The gear reduction motor can be used for microdrive system for EV charging pile lock, electric power steering (EPS), auto power tailgate, electric park brake (EPB), etc.
- Smart Home: smart lifting table, electric curtain
- Intelligent Robot: robot joint, intelligent escort robot, robot eye system, automatic feeder, building block drive system
- Consumer Electronics: all-screen phone camera, electric rotating camera for phone, intelligent portable photo printer for mobile phone, smart bike lock, automatic hair curler，e-cigarette cleaning part, vending machine, electric screwdriver
- Communication Technology: base station antenna
- Medical Technology: surgical stapling device
- Personal Care: fascia gun, electric foot grinder, treadmill pedal, waterreplenishing instrument, facial pore cleanser, face cleanser
If the rotary machine, like an engine or a motor, cannot provide you with the required output speed and torque in a small space, a micro gear motor or small gear motor should be put into use. While the parameters of most gear reduction motor need to be customized for the specific application scenario, you can come to ZHAOWEI for help, who provides all kinds of customized drive solutions for customers.
