Frequently Asked Questions
What is the typical lifespan of your brushless motors?
Our brushless motors are designed for longevity, typically working continuously for about 20,000 hours, which is ten times the lifespan of a traditional brushed motor.
In which industries are these motors primarily used?
They are widely applied in digital controlled lathes, medical instruments, automation equipment, laser machinery, and surveillance systems.
Do you offer customization for specific motor requirements?
Yes, we accept product customization to fit your unique mechanical or electrical specifications.
What is the advantage of brushless technology in terms of energy?
Brushless motors utilize frequency conversion technology, making them much more energy-efficient—consuming only about one-third of the power required by carbon brush motors.
What are the available voltage options for these motors?
We offer a range of rated voltages including 12V, 24V, 36V, 48V, and high-voltage 310V models.
What kind of technical support do you provide after purchase?
We provide a 1-year quality guarantee, free software, and technical training. Our engineers are available to provide professional support for any technical queries.
