Answer:Compared with asynchronous motors, permanent magnet synchronous motors have obvious advantages. It has high efficiency, high power factor, good capacity index, small size, light weight, low temperature rise, and remarkable technical effect, which can...
Answer:For the safety of amusement facilities, manufacturers usually use high-strength bolts to fix the motor. For commonly used motors, the number and size of the motor base have been determined before leaving the factory, and ordinary bolts can meet the d...
Answer:The magnetic circuit is similar to the circuit, and the magnetic steel and the power supply can be compared. Only the thickness is increased, and the magnetic flux corresponding to the residual magnetism remains unchanged, but the internal reluctance...
Answer:The motor shaft is hollow, the heat dissipation performance is good, and the weight of the motor can be reduced. In the past, the motor shaft was mostly solid, but because the stress of the motor shaft was often concentrated on the surface of the sha...
Answer:There is a certain relationship between the weight and performance of the motor, but it is not an absolute relationship. The performance of the motor depends on many factors, including the design of the motor, materials, processing technology, contro...
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.
