In the process of selling a discount, it may be due to a new takeover of the buying task. Do some buyers ask about the difference between speed drives and gear motors? So, I'm sending the dry matter today to everyone to discuss gear motors and inverter motors!

What is a geared motor?

It is an integrated speed reducer and motor. This integral body is also referred to as a gear drive or gear drive. Usually assembled by professional speed reducer manufacturer. After integration and assembly, it comes with the motor.

Gear motors are a power transmission mechanism used in applications that require high torque and do not require high torque. Examples: conveyor belts, coding machines, packaging machines, food equipment machines, sealing machines ... With the development of industry and factory automation, the demand for the use of speed reducers is increasing. There are many ways to slow down, but the most popular way is to use gears to slow down. This saves space and cost. Therefore, the reducer is also called a gearbox.

What is a variable speed drive?

The variable speed motor is the variable speed drive. In other words, it is a rotating machine that converts electrical energy into mechanical energy. It mainly consists of distributed electromagnetic or static coils used to generate a magnetic field and armor or rotor. The wire current flows and rotates under the influence of a magnetic field. Some of these machines can be used as motors or generators.

A variable speed motor is a device that converts commercial frequency energy (50Hz or 60Hz) into AC power at different frequencies to realize variable speed operation of the motor. The control circuit completes the control of the main circuit, and the rectifier circuit implements the AC power. Constant current. Then the middle part is converted from DC to DC. This circuit smooths the output of the rectifier circuit, and the inverter circuit converts DC to alternating current in reverse. For frequency converters that require a lot of calculations, such as frequency converters to control vector force, you may need CPU and corresponding circuits to calculate torque. Frequency conversion speed setting accomplishes the purpose of speed setting by changing the frequency of the stator winding power source.

A gear drive is a combination of a speed reducer and a motor. It is a power transmission mechanism that does not require very high speed. A variable speed motor is a device that converts electrical energy into mechanical energy and can convert commercial energy into AC energy at different frequencies.
