Q:Dc brushless motor and ac motor
Brushless dc motor, in fact, the result and ac motor, there is no essential difference between which is the direct current (dc) through electronic oscillation circuit into alternating current (ac), frequency is adjustable, commonly used to change the speed.
Q:How does the three-phase ac motor achieve constant power or constant torque output
Is generally frequency converter to realize, in the power supply of power frequency 50 hz, motor with frequency converter to belt, the inverter output below 50 hz, the motor is constant torque output, but in the inverter output above 50 hz, the motor is constant power output.
Q:The structure of the ac motor
Ac motor is a machine that transforms electrical energy into mechanical energy. The ac motor is composed of a stator winding that generates a magnetic field and a stator winding and a rotating armature or rotor. An electric motor is made from the phenomenon of force rotation in the magnetic field. Ac motor consists of stator and rotor and the stator and the rotor is to use the same power supply, so the direction of the current in the stator and rotor changes always synchronized, the coil in the direction of current changed, became the current in the electromagnet direction at the same time, according to the left hand rule, magnetic coil suffered direction invariable, the coil can continue to turn down. The communication engine is working with this principle. The main purpose of ac motor: ac motor is more efficient, no smoke, no smell, no pollution, no noise. Due to its series of advantages, it is widely used in industrial and agricultural production, transportation, national defense, commercial and household electrical appliances, medical equipment and so on.
Q:Comparison between ac motor and dc motor
The advantages of a dc motor The dc motor has good starting characteristics and speed regulating characteristics The torque of dc motors is greater It's cheaper to repair. Dc motor is more energy-efficient than communication.
Q:Control the power ac motor with thyristor or relay?
No problem, the instantaneous current is considered in the design of relays. You don't have to worry about it. When selecting a type, you should think about some surplus. It is also possible to consider using a converter, which can now be replaced by a variety of functions, and has a soft start function.
Q:According to the power of motor, how to select the contactor and switch?
According to the power of the motor, the current of the motor is about the value of the electric current, the ac contactor capacity should be more than twice as long as the electric current, and the circuit breaker is more than 1.4 times the electric current.
Q:Single phase single capacitance ac motor three wires wrong
The single phase motor is divided by the main winding and the starting winding, and the wrong turn can also be turned, but the electric opportunity quickly overheat and damage, the proposal to seek a professional to show you.
Q:Why does the motor need capacitance when the machine starts?
Only for single phase ac motor, because a single winding is unable to form a rotating magnetic field, the electric capacity of a rotating magnetic field is formed after phase-shifting three-phase don't need to, so it can synthesize a rotating magnetic field
Q:Current ac motor has completely replaced dc motor
No matter Powerful electric cars can communicate without dc Small power hard drives, stripper motors in the optical drive, not all dc
Q:Why is dc motor less efficient than ac motor
Dc motor speed regulation is simple, but use case is limited. Ac motor speed regulation is relatively complicated, but it is widely used because of ac power supply.
