Introduction
Not all fan motors are created equal. For manufacturers of table fans, stand fans, wall fans, exhaust fans, and industrial ventilation equipment, the CBB61 capacitor motor is the industry standard. But what makes this motor type so versatile, and how do you choose the right one for your application?
This guide provides a comprehensive overview of CBB61 capacitor motors across different fan applications, including power ratings, capacitor selection criteria, and practical selection tips for B2B buyers and manufacturers.
What Is a CBB61 Fan Motor?
A CBB61 fan motor is a single-phase AC induction motor that uses a CBB61 run capacitor for phase shifting and speed regulation. The CBB61 capacitor is a metallized polypropylene film capacitor—non-polarized, self-healing, and designed for 50Hz/60Hz AC power supply. It works by creating a phase shift—typically around 90 degrees—between the main winding and the auxiliary winding, which produces the rotating magnetic field that starts and runs the motor.
CBB61 Capacitor Motor Selection by Fan Application
Application | Power Range | Key Requirements |
Table Fans | 15–60W | Low noise, stable rotational speed |
Stand Fans (Pedestal Fans) | 30–80W | Strong airflow, easy adjustment |
Box Fans | 30-50W | Long airflow range, high durability |
Wall Fans | 20–70W | Space-saving, easy installation |
Exhaust Fans | 5–40W | Compact size, high exhaust efficiency |
(3-in-1) Industrial Fans | 55–150W | High air volume, dustproof and waterproof |
CBB61 Capacitor Selection by Fan Motor Type
Fan Motor Type | Power Range | Recommended CBB61 Capacitance | Voltage Rating |
Table Fan Motor | 20-40W | 1.2μF – 1.5μF | 450V AC |
Stand (Pedestal) Fan Motor | 30–80W | 1.2μF – 4.0μF | 450V AC |
Box Fan Motor | 30-50W | 1.2μF – 2.0μF | 450V AC |
Wall Fan Motor | 30–90W | 1.0μF – 3.0μF | 450V AC |
Exhaust Fan Motor | 5–40W | 1.0μF – 1.5μF | 450V AC |
(3-in-1) Industrial Fan Motor | 55–150W | 2.0μF – 6.0μF | 450V AC |

General CBB61 Capacitor Selection Principles
When selecting a replacement or spare CBB61 capacitor, you must pay attention to three key parameters:
Capacitance (μF): Must strictly match the nominal value of the original capacitor. A value that is too high or too low can lead to starting difficulties, abnormal torque, motor overheating, or even motor burnout.
Rated Voltage (V~, AC voltage): Must be equal to or higher than the nominal voltage of the original capacitor (common ratings include 250VAC, 350VAC, 400VAC, 450VAC, etc.). Selecting a rating that is too low may result in capacitor breakdown.
Rated Frequency (Hz): Typically 50/60Hz; this must match the power supply frequency of the motor.
Conclusion
CBB61 capacitor motors are the most versatile and widely used choice across table fans, stand fans, wall fans, exhaust fans, oscillating fans, and industrial fans. For B2B buyers, understanding the relationship between motor power and capacitor selection is critical for ensuring product performance, reliability, and service life.
Partnering with a manufacturer that offers both standard and custom CBB61 motor solutions ensures you get the right motor for your specific application—with the correct capacitor configuration from the start.
