FAQ
Q1: Is CBB61 a start capacitor or a run capacitor?
A: CBB61 capacitors are typically used as motor run capacitors, designed to support stable operation of single-phase AC fan motors during normal running conditions.
Q2: What makes CBB61 suitable for fan motor circuits?
A: CBB61 capacitors offer stable phase shifting and consistent capacitance, which are essential for maintaining smooth rotation and balanced torque in fan motors.
Q3: Can CBB61 capacitors be used in variable-speed fan systems?
A: Yes. CBB61 capacitors are commonly applied in multi-speed fan circuits, where different capacitance values are used to control motor speed levels.
Q4: How does a CBB61 capacitor affect fan motor efficiency?
A: By providing proper phase displacement, a CBB61 capacitor helps improve motor power factor and running stability, contributing to efficient fan operation.
Q5: What factors should be considered when sourcing CBB61 capacitors for production?
A: Buyers should consider capacitance stability, voltage rating, consistency between batches, and supplier quality control, especially for OEM or large-volume applications.
