Start capacitor: to start the single-phase AC induction motor electrolytic capacitor or polypropylene, polyester capacitors.
Principle of start capacitor
Single-phase single-phase flow through the motor current can not generate a rotating magnetic field, the need for capacitors for phase separation, the purpose is to make the two winding current generated near a phase difference of 90 °, to produce a rotating magnetic field.
Capacitive induction motor has two windings, namely start winding and run winding. The two windings 90 degrees in space. On the start winding in series with a large capacitance, when running winding and start winding through the single-phase AC power, the role of the capacitor so that the start winding current in the current time than running ahead of the winding angle of 90 degrees, the first arrival maximum. Forming two identical magnetic field pulses in time and space, so that the air gap between the stator and the rotor produces a rotating magnetic field, under the action of the rotating magnetic field, induced current, rotor current and the rotating magnetic field generated in the interaction electromagnetic torque, the motor spin.
For single-phase motor can be automatically rotated up, we can add a start winding in the stator, the start winding and the main winding 90 degrees in the space, the start winding connected in series to a suitable capacitor, so that the current in the primary winding approximately 90 degrees in phase, i.e. a so-called phase separation principle. Such two phase difference of 90 degrees in electrical flow into two temporally different by 90 degrees in the winding space, will produce (two-phase) the rotating magnetic field in space. In this rotating magnetic field, the rotor will automatically start, after starting, until a certain speed rise when mounted on the rotor by means of a centrifugal switch or other automatic control means the start winding is disconnected, and only the main winding during normal operation the work. So, start winding can be made short work. But there is a lot of time, start winding is not disconnected, we call this motor capacitive single-phase motor, steering motor to change this, by changing the position of a capacitor connected in series to achieve.
Start capacitor is calculated
Single-phase motor running capacitor is calculated: C = 1950I / Ucos∮ (microfarads)
I: motor current, U: supply voltage; cos∮: power factor, taking 0.75,1950: Constant
Starting capacitors are generally run by 1-4 times the capacitance calculation
