What is a drive motor resolver? Advantages of drive motor resolvers

What is a drive motor resolver? The drive motor resolver is an analytical tool for the operating principle of the motor. It is used to analyze the changing laws of the electromagnetic field when the motor is running. It consists of two parts: a stator and a rotor. The windings on the rotor and the w

Share a function block for motor star-delta start written in SCL language

The national standard stipulates that three-phase asynchronous motors are not allowed to start directly under the following two circumstances:① The rated capacity is greater than 7.5kW;② When the motor is powered by a special transformer, The capacity is greater than 20% of the transformer capacit

Can the speed of a DC motor be controlled using a three-phase fully controlled bridge rectifier circ

Experimental principles of three-phase bridge type fully controlled rectification and DC motor speed regulation The three-phase bridge type fully controlled rectification circuit can use a trigger to control the conduction of the rectifier, thereby changing the direction and magnitude of the curren

The link of the motor to transmit energy – introduction to magnetic flux

In an asynchronous machine, the transfer of energy depends on magnetic flux. This is considered from the perspective of energy conversion. To drag the load, sufficient mechanical energy is required, and this mechanical energy must be obtained from electrical energy. , and the link of transmission is

Detailed explanation of motor forward and reverse circuit and common faults

The application of motor forward and reverse is very extensive, and it is also one of the required items for the low-voltage electrician practical examination. Only when we fully understand its working principle and action process can we flexibly use it in practical work. And when a fault occurs, we

Faults and Treatment Methods of Motor Stator Windings

The stator winding of the motor is the part that generates the rotating magnetic field, and its failure will directly affect the normal operation of the motor. Common faults of stator windings are as follows:1. MoistureIn the motor storage location or workplace, if the humidity is high, the motor ma

Why does it affect the work of other electrical equipment when the motor starts?

Let’s summarize the existing answers first: (Please add if you haven’t said everything) 1. The power of the motor is greater than 10kW; 2. The power of the motor is greater than 50kW; 3. The power of the motor is greater than 20% of the transformer capacity;

Software Decoding and Hardware Decoding Method of Motor Position Sensor

About the topic of the motor position sensor, the following two questions are often asked, and I will sort them out here:What is "hardware decoding"? What is "software decoding"? The resolver position sensor has 6 lead connectors, which are: input (excitation +, excitation -), ou

What is the resolver zero deflection angle? Why does each motor need to calibrate the resolver zero

The zero deflection angle of the motor position sensor (that is, the zero deflection angle or initial angle of the resolver) is crucial to the accuracy of the motor output torque. For the new energy 150KW drive motor, when the resolver zero deflection angle has an electrical angle offset of +/-2, it

What does the motor resolver mean? The working principle of the motor resolver

1. Principle Resolver is a position sensor commonly used in motor control. The function of the resolver is to accurately measure the position, speed and direction of rotation of the motor rotor , transmit these signals to the electric control, and the motor is controlled by the control algorithm o
