- Small tolerance of +/-5% for stable values over time, without capacity loss
How it works and how to install it
The capacitor stores electrical energy and releases it at motor startup, providing the necessary torque for initial rotation. It is fixed to the motor or appliance chassis using the screw at the top, and the two wires are connected to the corresponding terminals in the electrical diagram. Installation requires electrical knowledge and must be performed by a certified electrician, observing the voltage values indicated on the casing.
Frequently Asked Questions
How do I know if the motor capacitor is faulty?
Signs of a worn capacitor include difficult starting or complete refusal of the motor to start, increased operating noise, or unexpected shutdown. Checking with a multimeter confirms the actual capacity.
Can I use a 40uF capacitor for any electric motor?
No, the capacity must match the motor's specifications. Check the appliance label or technical manual for the correct microfarad value and power supply voltage.
Why are there multiple voltage values on the capacitor?
The values 400V, 450V, and 500V indicate the estimated lifespan under different thermal stresses. For continuous use, choose 450V, which offers an optimal compromise between reliability and longevity.
