Answer：When the brushless DC motor is working, it will cause commutation torque fluctuations. How to suppress the torque fluctuations? The following editor will introduce several methods to suppress the torque fluctuations caused by current commutation.
Answer：There are many reasons for the torque fluctuation of brushless DC motors, which can be divided into the following aspects: torque fluctuation caused by the electromagnetic torque generation principle, torque fluctuation caused by current commutation,...
Answer：The brushless motor removes the brush. The most direct change is that there is no spark generated when the brushed motor is running, which greatly reduces the interference of sparks to remote control radio equipment.
Answer：Brushless motors use square wave self-controlled permanent magnet synchronous motors, which are very similar to three-phase asynchronous motors and have great advantages in performance; brushless motors have low interference, low noise, and long life...
Answer：With the rapid development of power electronics technology and new semiconductor devices, AC speed control technology has been continuously improved and improved. The gradually improved frequency converters have been widely used in AC motors with the...
Answer：It is a key and pivotal component in the process of mutual conversion of mechanical energy and electrical energy in the motor. For a generator, it is the component that generates electromotive force, such as the rotor in a DC generator and the stator...
Answer：PTC and PT100 are commonly used thermal components in motor windings. Both are thermal resistors, and their resistance values will change with changes in temperature. But the functions and uses of the two are different.
Answer：The faults of three-phase asynchronous motors can generally be divided into two categories: one is electrical faults, such as faults of various types of switches, buttons, fuses, brushes, stator windings, rotors and starting equipment; the other is I...
Answer：Motors are our common electrical equipment, so how can we simply measure the quality of motors? Motors are electrical equipment that we often come into contact with, and they are also the most basic equipment. This is considered a basic skill, and it...
Answer：The motor is the most common electrical component in our industrial control. Many students are not sure about the wiring method of the motor. How to connect it, and they are still confused when searching online. Today we will explain the connection m...
