Q:What is the electrical Angle in the motor? What does it have to do with mechanical angles

Motor for each pole on the stator inner circle of the Angle is 360 ° / p refers to the actual space geometry Angle, this Angle is called the mechanical point of view. In the motor of the number of quadrupole and above often take a pair of polar Angle 360 ° of the defined as electricity, this is because the winding induction electric potential changes in a cycle of 360 °.

Q:Is the synchronous motor not communicating? Why do you say that brushless dc is a type of synchronous motor? Exclude o

Ontology is an alternating current, motor also similar, but the dc supply is converting ac square-wave brushless motor winding, permanent magnet synchronous motor is to convert alternating current (ac) to supply sine wave with motor winding. It's just electrical control. Can't see from the outside!

Q:The difference between dc brushless motor and ac servo motor

Simple dc brushless motor can not do position control and can only do speed control. Ac servo can do position control and other kinds of control.

Q:How does the ac motor in soybean milk machine speed up?

From the electric road, the two, three, and five are relays, which control the motor switch with the amplifiers of the triode, only two gears, and there is no difference in speed. As far as I know, the soybean milk machine speed is controlled by series pressure control of electric component, this circuit diagram does not have this kind of setting, on the manual of the shanzhai products are generally not complete, in fact there is no speed difference, just play when dried beans will be loud, it sounds like a high speed.

Q:Please communicate the motor. It is possible to speed the speed with a governor

Many household electric fans using bidirectional thyristor phase shift control of motor speed, this kind of speed is actually reduce the input current make motor with fixed running quickly and can only reduce the speed. Like dimming lamps, they are forced to regulate.

Q:Why does a single phase ac motor have to be a capacitor to start running?

Plus, the purpose of the capacitance is 90 degrees, the phase lag is not string of a phase winding capacitance, current phase Angle is zero, the other phase winding series capacitor after the phase Angle is 90 degrees, two phase winding to produce electric potential (torque).

Q:Does the step motor belong to ac motor or dc motor?

Step motor should be ac motor, and stepper motor is an actuator which converts electrical pulse into angular displacement. Popular point: when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle (and the step Angle). You can control the amount of angular displacement by controlling the number of pulses, so that the target is accurate. At the same time, you can control the speed and acceleration of the motor by controlling the pulse frequency.

Q:What is the difference between alternating current motors and dc motors?

Upstairs is a little irrelevant answer, the first people ask is the difference, again is the motor, not the generator! How it works: Dc motor installed a constant magnetic field, after the stator coil zhongtong current is generated electromagnetic force, so they will move, but the direction of the electric current to change, so will generally use brush, contact with the terminal. So the cost is higher. It is commonly used in servo motor, measuring motor and excitation motor. The ac motor has only one winding and the rotor is squirrel-cage. When a single-phase sinusoidal current in the stator winding, the motor can produce an alternating magnetic field, the magnetic field strength and direction interplanting sine law of change at any time, but is fixed on the spatial orientation, say again so the magnetic field is alternation pulse magnetic field. This alternation pulse magnetic field can be decomposed into two at the same speed and direction of rotation are instead of a rotating magnetic field, when the rotor static, the two rotating magnetic field generated in the rotor torque of two equal and opposite, making synthetic torque is zero, so the motor can't rotate.

Q:Is permanent magnet synchronous linear motor is ac motor or dc motor?

Permanent magnet motor, general is small dc motor, and ac motor, generally do not have dc small, the excitation that USES is line excitation also. It's not permanent magnetism. Like some razor, small motor is permanent magnet dc motor, some dc output of the generator, is also a permanent magnet, some also dc generator output, but it was all in after a dc generator output, and is not directly the output direct current.

Q:What happens to the capacitance of ac motor

A little bit is ok, if big, it is easy to burn the machine, you can try for yourself, change the new capacitor to take a look. (less turn for a moment is ok) and see if it is immediately fever, if, so before you the motor or a large capacitance, but I think you are still in a first try out as large as before,
