The following are some common questions from customers. If you don’t understand or have other questions, please contact us and we will provide you with detailed answers!
1. What are the types of brushless motors? What are the minimum and maximum outer diameters that can be achieved?
The outer diameters of brushless motors are 42mm, 57mm, 60mm, 80mm, 86mm and 110mm. The smallest outer diameter 42mm is currently in production, and 36mm and 28mm outer diameters are being developed in the future. The largest outer diameter is currently 110mm in production. Yes, after developing the 130 and 160 brushless motors.
2. What is the minimum power of the brushless motor and the maximum power of the brushless motor in watts?
At present, the minimum power of brushless motors is 15W, and the maximum can achieve 3KW.
3. Can brushless motors be equipped with gearboxes? Can brakes and encoders also be equipped?
Brushless motors can be equipped with gearboxes, brakes and encoders. Gearboxes can be divided into planetary gearboxes, eccentric gearboxes and turbine gearboxes. The brakes are divided into power-off brakes and power-on brakes. Encoders can be divided into photoelectric encoders. And magnetic encoder two kinds.
4. What is the difference between brushless and brushed motors? Can a brushless motor be turned on when it is energized like a brushed motor?
The biggest difference between a brushless motor and a brushed motor is that the brushless motor is electromagnetically commutated, and the brushed motor is commutated between the carbon brush and the commutator (also called commutator). The life of the brushed motor depends on the carbon Brushes, and the life of brushless motors depends on the bearings and Hall elements. The brushless motor must run through the drive circuit. If it needs to be energized, it can be turned. Our company also provides a brushless motor with a built-in drive.
5. What is the efficiency of general brushless motors?
The efficiency of brushless motors produced by our company can generally be between 75% and 85%.
6. What is the general life of brushless motors? What brand of bearings does your company choose for general brushless motors?
The life of a brushless motor is generally 20,000 hours of continuous operation. The life of a brushless motor mainly depends on the bearings and Hall elements. The bearings and Hall elements of our company's brushless motors are imported from abroad.
