Features and applications of low -speed torque motors
1. DC motor
DC motors are a common electric motor. It has the advantages of large startup torque, wide speed adjustment range, and good reversal performance. DC motors need to be maintained on a regular basis, and it is easy to produce shortages such as brushing sparks and high noise.
2. AC asynchronous motor
AC asynchronous motor is one of the current commonly used motors. It has the advantages of simple structure, high reliability, and low maintenance costs. AC asynchronous motors have small torque torque and difficult to achieve accurate speed regulation.
3. Step motor
Step motor has the advantages of high positioning accuracy, fast response speed, and no sensor. Step motors cannot run overload, noise, and prone to leakage.
4. Low -speed large torque motor
Low -speed torque motor is a motor specially used for low -speed and high -torque occasions. It has the advantages of high -speed torque, narrow speed range, and high efficiency. Low -speed torque motors are suitable for occasions that require large torque starting, such as cranes and rolling machines.
There are the following types of low -speed large torque motors on the market
(1) DC deceleration motor reduces the speed through the deceleration device, thereby increasing the torque. DC deceleration motors have the advantages of small volume, high efficiency, and large startup torque.
(2) AC reduction motor reduces the speed through the deceleration device, thereby increasing the torque. AC motors have the advantages of simple structure and low maintenance costs.
(3) Permanent magnet synchronous motor has the advantages of high efficiency and low noise. The permanent magnet synchronous motor is often used in the occasion that requires accurate control.
In short, different types of motors have advantages and disadvantages, and the appropriate motor needs to be selected according to specific needs. For low -speed torque occasions, you can choose DC deceleration motor, AC deceleration motor or permanent magnet synchronous motor.
The choice of permanent magnet motor and brushless motor
The permanent magnet motor uses the magnetic field of the permanent magnet to generate rotating torque, which has high efficiency and reliability, and its structure is simple and convenient. Therefore, in many application scenarios, permanent magnet motors are the first choice. For example, permanent magnet motors are widely used in the fields of electric vehicles and wind power.
Brushless motor is a type of electron -to -direction motor. It replaces traditional mechanical wiper through electronic wiper, so it has higher control accuracy and response speed. In addition, brushless motors are also highly efficient, low noise, and low maintenance costs. Therefore, in application scenarios that require high precision and high efficiency, brushless motors are a better choice. For example, in the fields of CNC machine tools, industrial robots, brushless motors are widely used.
Therefore, if you are looking for an efficient and reliable motor, the permanent magnet motor may be more suitable for you; if you need high -precision and high -efficiency motors, the brushless motor may be more suitable for you.
