Question
Download Solution PDFThe capacitor commonly used for ceiling fan motors has a value of 2.3 μF. The type of capacitor is used __________.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- The single-phase induction motor is not self-starting. Hence, it requires an auxiliary means or equipment to start the motor.
- Mechanical methods are impractical and, therefore the motor is started temporarily converting it into the two-phase motor.
- Commonly used starting methods for a ceiling fan is a permanent capacitor or single value capacitor motor.
- The permanent capacitor motor also has a cage rotor and the two windings named as main and auxiliary windings.
- The capacitor C is permanently connected in the circuit both at the starting and the running conditions.
- It is also called as a single value capacitor motor as the capacitor is always connected in the circuit.
- A paper capacitor is used in the permanent capacitor motor as an electrolytic capacitor cannot be used for the continuous running operation of the ceiling fan.
- The cost of the paper capacitor is higher, and the size is also large as compared to the electrolytic capacitor of the same ratings.
