In the process of selling a reducer, it may be due to a new procurement procurement task, some purchases ask the difference between speed motors and gear motors? So send everyone dry today and talk about gearmotors and inverters!

What is a gear motor?

It is an integrated type of motor and speed reducer. An integrated body of this type is also commonly referred to as a gear motor or a gear motor. It is usually assembled by a professional speed reducer factory. After integration and assembly, it comes with the motor.

Gearmotors are power transfer mechanisms used in applications that require high torque and do not need to be too high. Examples: Conveyor belts, encoders, packaging machines, feeding equipment, sealers ... And with the development of the industry and the automation of factories, the demand for the use of speed reducers is increasing. There are many ways to slow down, but the most common is to use gears to slow down. This saves space and costs. Therefore, the reducer is also called a gearbox.

What is a variable speed motor?

The variable speed motor is a variable speed motor. Simply put, it is a rotating machine that converts electrical energy into mechanical energy. It consists mainly of an electromagnet winding or dispersion stator winding to generate a magnetic field and a rotating armature or rotor. The current in the wire passes through the action of the magnetic field and rotates. Some of these machines can be used as electric motors or generators.

A variable speed motor is a device that converts a commercial frequency power source (50 Hz or 60 Hz) into a multi-frequency AC power source to perform variable speed operation of the motor in which the control circuit Complete the main circuit control. The rectifier circuit converts AC to DC, the intermediate DC circuit smooths the output of the rectifier circuit, and the inverter circuit reverses DC to AC. For frequency converters, such as vector control inverters, which require a lot of calculations, a CPU for the calculation of the torque and a corresponding circuit may be required. Frequency conversion speed adjustment achieves the purpose of speed adjustment by changing the power supply frequency of the motor stator winding.

A gearmotor is a combination of a speed reducer and a motor. A power transmission mechanism that does not require high speed. A variable speed motor is a device that converts electrical energy into mechanical energy, which can convert commercial energy into AC energy of various frequencies.
