Q:What subjects should be included in the purchase of ac contacts and motors?: These two should belong to the fittings, not be used alone, should be repaired equipment to use, so direct in the period of cost - repair cost is ok. Hope to help you!

Q:How does ac motor speed control: Buy the speed adjustment machine ~ 4 files ~ the external one governor ~ can be adjusted More expensive,

Q:The rated current of a single phase ac motor is several times that of an empty current.: That's not how you understand it. 220V depends on whether you are a three-phase or single phase. For the three-phase P = 1.732 * U * power factor, for a single phase, P = UI. In other thermal relays we typically press 0.95-1.05 motor rated current. It doesn't seem to have been selected by 1.2 times.

Q:Why does the motor need capacitance when the machine starts?: Only single phase ac motor USES capacitance, dc motor and three-phase ac motor do not need. The two single-phase motor coil does not produce a rotating magnetic field, must be in one of the series capacitance on the coil, make this branch of the current in another coil current in advance, the ability in a rotating magnetic field between the two coils, rotor rotation.

Q:What is the difference between the excitation winding of ac motor and the armature winding?: Motor learning definition "armature" as the "main power circuit", as long as you think about the power of the stator loop or rotor circuit of large power, the big is the armature. The power is the voltage X current. Only the synchronous generator and the synchronous motor have excitation winding and armature winding. The general ac asynchronous motor is not excitation winding. Squirrel-cage asynchronous motor points and winding type two kinds big, the same stator winding structure, the squirrel-cage rotor cage bar, wound rotor rotor coil is an external device (can change the rotor impedance to realize variable speed). The "armature winding" is the "main power circuit" of the motor. Which power of the rotor and stator coil is "armature", needless to say, most stator coils are "armature winding".

Q:How to control ac motor with single-chip microcontroller: First of all, you have to make sure that you have a two-way flow of alternating current motors. For example, using a single piece of the triode drive relay to control the motor's positive and backward rotation, as in the case of the main parasymmetrical single tap. The problem with this control circuit is that you can't control the motor stop! Moreover, the steering is controlled when the motor is rotated The motor may cause damage due to inertia. In the figure, the added level 1 stop control (1) (2), and steering control besides can control the motor stopped, also can be in to control motor rotation to insert the stop control, avoid damage to the motor inertia torque motor. Of course, if you are using two limit switches to control the motor's one-way work, you can use the image above.

Q:What happens to the capacitance of ac motor: The starting capacity of a single phase ac motor is not too large, and the oversize will cause the start torque Angle to deviate from the maximum, and the secondary winding current consumption increases. Too small to start the motor, the motor will not run for a long time!

Q:The rated speed of ac motor: Synchronous speed of motor is 60 * frequency/magnetic log 8 extreme: 60 * 50/4 = 750 RPM, and asynchronous RPM is slightly reduced by about 735 RPM 6 extreme: 60 * 50/3 = 1000 RPM/min, the asynchronous RPM is slightly reduced by about 980 RPM Extreme: 60 * 50/2 = 1500 RPM, and asynchronous RPM is slightly reduced by around 1475 RPM Extreme: 60 * 50/1 = 3, 000 RPM, and the asynchronous speed is slightly reduced by about 2970 RPM "Ac motor" is a machine used to realize mechanical energy and exchange electrical energy. Ac motor has become the most commonly used electric motor due to the huge development of ac power system. Compared to the ac motor and dc motor, with no commutator (see dc motor commutator), so the simple structure, easy fabrication, quite strong, easy to make a high speed, high voltage, high current, the large capacity motor. Ac motor power covers a wide range, ranging from a few watts to several hundred thousand kilowatts and even a million kilowatts. In the early 1980s, the largest turbine generator was 1.5 million kilowatts.

Q:Is the inductance of the stator winding of single phase ac motor constant? Does the inductance of the stator winding change when the motor turns?: This is a conceptual error! Inductance is the fixed index of inductance element! Like resistors of resistance! Capacitance value! The inductance is not inductive! Not electromagnetic induction strength! It doesn't change when it's fixed! The inductance is the design data! Inductive and inductive strength is the actual application data!

Q:The motor in the hair dryer is ac motor, or dc motor: If an electric blower is connected to a 220V power supply, it is the ac motor.
