Answer：The driving force for developing an ultra-high power density motor drive system is: under the same volume or mass, the output power is greater, the overtaking acceleration ability and high-speed continuous driving ability are stronger, and excellent ...
Answer：According to the way the air gap magnetic field is established, it can be divided into two categories: 1,Electromagnetic (series excitation) DC motor: its air gap is generated by direct current applied to the excitation winding. (such as ZC-10K seri...
Answer：Inverter is a motor control device with the highest technical content, the most complete control functions and the best control effect in the field of modern motor control. It adjusts the speed and torque of the motor by changing the frequency of the...
Answer：Servo motors are used in many fields, such as CNC machine tools, printing equipment, packaging equipment, textile equipment, laser processing equipment, robots, automated production lines and other equipment that require relatively high process accur...
Answer：We know that cutting the magnetic lines of force by wires can generate an induced potential, and connecting the wires into a closed loop will allow current to flow. The generator works based on this principle.
Answer：The DC motor can convert mechanical energy into DC electrical energy as a generator, and can also convert DC electrical energy into mechanical energy as a motor. DC motors are generally used as DC power sources. Due to the development of thyristor t...
Answer：First of all, it should be judged whether it is caused by mechanical or electrical reasons? The method is: connect the power supply, there is an abnormal sound, cut off the power supply, if the abnormal sound still exists, it is a mechanical failure;...
Answer：With the improvement of global industrial automation, intelligence and people's living standards, motors will be more and more widely used in the fields of automobiles, household appliances, electronic audio and video, information processing equ...
Answer：One of my friend's equipment is not capable enough. In view of economic considerations, I don't plan to buy the whole equipment with higher power, but want to change to a motor with higher power, hoping to achieve the most economical equipm...
