AI Customer ServiceTypical Motor Driver Board Showing Large Bulk Capacitors Experienced engineers often use general guidelines about bulk capacitance to select the capacitor values. One such guideline says to use at least 1 to 4μF of capacitance for each Watt of motor power.
Some motors are electronically controlled and do not need capacitors. The need for capacitors must be handled a bit differently if there is harmonic distortion in the power system. Harmonic voltages in the distribution system can cause resonance oscillation currents between the capacitors and the motor and transformer inductance.
Power Factor correction by capacitor bank installation will reduce the current consumption of a particular motor. I have a motor with the followings specs: During pump performance test, my motor was running at 420Amps ( short time ) but we still unable to get the required pressure for the pump. Hence, we have to reduce the motor amps further.
The capacitor bank is used not to improve the P.F of motor itself; it is used to improve the P.F of the system. Even you add the capacitor bank at the motor terminal; it will reduce the current through the motor cable but not the current (of course the magnitude of the current) drawn by the motor. What is the S.F (Service Factor) of the motor?
One such guideline says to use at least 1 to 4μF of capacitance for each Watt of motor power. For example, a motor which draws 10 Amps from a 12V supply has a power of 120 Watts, leading to bulk capacitance of 120 to 480μF, using this general guideline. We dig a little deeper and see what further discussion supports those estimates.
It is common to include large bulk capacitors as part of the motor driver design. These bulk capacitors act as a local reservoir of electrical charge to smooth out the motor current variation.
