CD60 Motor Start Capacitor The Current Interacts With The Rotating Magnetic Field
- Jul 18, 2017 -

No matter what kind of capacitance, in the beginning of the motor has a starting role. But when the motor reaches the rated speed of 75 [%] or so, the starting capacitor is automatically disconnected by the centrifugal switch, while the running capacitor is to accompany the motor to continue to work. CD60 Motor Start Capacitor process, in fact, is the "column phase" process. Because the single-phase motor and three-phase motor is not the same, there is no phase difference, can not produce a rotating magnetic field. The role of the capacitor is to make the CD60 Motor Start Capacitoring winding current in time and space, ahead of the operation of the winding 90 electrical angle, the formation of phase difference. Among them, the running capacitor also plays a role in balancing the current between the main and auxiliary windings. Starting capacitor is a short time for the work, pressure requirements above 250V on the line, and the operation of the capacitor to work for a long time, requiring more than 400V pressure.

You say "electric ho" is the kind of drill hole drilling? This depends on the general motor or asynchronous motor. In the former it is the speed of the capacitor, generally only a few UF, the latter capacitor is running, mostly below 20UF. Of course there are large, which mainly depends on the size of the motor power. On the "smoke" problem, the motor should be too large current, winding overheating so short-circuit burned, most of the capacitor is not the problem. Capacitive short-circuit breakdowns rarely see smoke, and sometimes can smell a special smell.

For you that kind of motor, almost no can not buy the accessories, capacitors generally as long as a few dollars a dozen yuan. Repair technology is not demanding, ordinary motor repair workers can generally be resolved.

Start capacitor is to make a single CD60 Motor Start Capacitoring coil in the start when the power, start off,

Running capacitor is to allow the motor to run in the capacitor compensation, so the start capacitor can not be less, and the running capacitor can not.

AC motor rotation depends on the current generated by the rotating magnetic field. Three-phase motor flows through the phase difference of 120 degrees of three-phase current, can produce rotating magnetic field. And single-phase motor flow through the single-phase current can not produce a rotating magnetic field, you need to take a certain method to produce a rotating magnetic field, with the capacitor is one of the methods, but also the most common method.

The capacitance is used for phase separation in order to produce a phase difference of nearly 90 ゜ in the current in the two Rao groups to produce a rotating magnetic field. Three-phase electricity, the current between the two phases itself has a phase difference, do not split phase.

Capacitive induction motors have two windings, namely, start winding and operating windings. The two windings are spatially different by 90 degrees. A capacitor with a larger capacity is connected in series with the windings. When the winding and the starting winding are connected via a single AC power,CD60 Motor Start Capacitor the current in the starting winding is in time than the current of the operating winding by 90 degrees. value. Two identical pulsed magnetic fields are formed in time and space, and a rotating magnetic field is generated in the air gap between the stator and the rotor. Under the action of the rotating magnetic field, the induced current is generated in the motor rotor, and the current interacts with the rotating magnetic field Electromagnetic field torque to rotate the motor.
