Q:How can a DC motor be changed into a three-phase AC motor with good performance?
DC motor is changed to three-phase AC motor:Direct current motors and AC motors are generally unable to replace each other. This is because the DC motor and AC motor of the external characteristics of comparison, there are still very different, compare the relevant information will know.
Q:What's the difference between a three-phase AC motor and a two-phase one?
A three-phase induction motor consists of a stator and a rotor. Its stator winding is a three-phase symmetrical winding with symmetrical power supply. A two-phase motor is used to specify a motor with a 2 phase winding. Two-phase motor is divided into two categories: drive and servo. The Dan Xiang asynchronous motor used in most household appliances and small appliances belongs to two phase drive motors. Two phase servo motor for control, the stator's two phase windings are exciting windings and control windings respectively, with a space difference of 90 degrees of electric angle.
Q:How does the battery of the electric car drive the AC motor?
In addition, this type of motor does not require inverters, the motor itself is a low voltage motor. Want to help you, the specific work principle can refer to the ordinary brush DC motor, the difference is coil winding current commutation instead of controller electronic commutation.
Q:Does the DC motor work the same as the AC motor?
DC motor has fast response, large starting torque and rotational speed from zero to the rated speed with rated torque available performance, but the advantages of DC motor is a DC motor because of its disadvantages, to generate performance under rated load torque is constant, the armature magnetic field and the rotor flux to maintain constant 90 degrees, this by brush and commutator. Carbon brush and commutator motor rotates in sparks, so in addition to cause toner component damage, use is restricted.
Q:How to make the AC motor stop rotating rapidly?
Electromagnetic brake, load and DC braking or braking circuit of DC power consumption
Q:In the main circuit of AC motor, fuse can be used as short circuit protection, can it play the role of overload protection at the same time, why?
Short circuit protection: some devices can monitor abnormal conditions in the work circuit (such as short circuits). When abnormal happens, the circuit is cut off and alarm is sent to prevent further expansion of the damageA typical short circuit protection is a fuse. When the short circuit is short, the current is very high. When the fuse is blown, the circuit will be out of power.Overload protection: to prevent the main power line from overload protection caused by overheating damage and installation of overload protection equipment
Q:Main structure of AC motor
The core is: the magnetic circuit of the motor, the iron core is fixed on the frame, a silicon steel sheet surface insulation Die pressing, punching a uniform circular notch of silicon steel sheet, for stator winding. Stator winding: the circuit part of an electric motor.
Q:The difference between DC motor and AC motor in electric stacker
Disadvantages of DC motor1. direct current motor manufacturing is more expensive2. carbon brush
Q:Why is AC motor control more difficult than DC?
Motor control, generally refers to speed regulation".AC motors are different from the mechanical characteristics of direct current motors,The mechanical characteristics of the DC motor are 1 slightly downward inclined "straight lines", the relationship between its speed and torque (characteristic) is relatively "hard", and it can easily change its speed by changing the power supply voltage of the motor;
Q:Isn't the starting winding symmetrical? If it's symmetrical, it's also an alternating pulsating magnetic field, how can you drive the rotor?
Because the magnetic field will not rotate (single phase winding and three-phase current phase difference of 120 DEG to produce a rotating magnetic field, so the starting winding), the working principle is in the starting winding current is generated through nearly 90 degrees of the magnetic field produced by a capacitor, the rotating magnetic field.
