Mechanical Dimension
Brushless motors work by alternating the polarity of the windings on the interior of the motor. The magnetic fields created when the coils are generated exert a push/pull force on the permanent magnets arranged around the outside of the casing.
Based on all this advantages, our company specializes in producing hybrid stepping motors, DC brushless motors, servo motors, gearbox motors and so on. The products are applied in robots, packing machinery, textile machinery, medical instruments, printing machinery, intelligent logistics equipment... Hetai also sends its products to USA, Europe, Southeast Asia and all-around China.
The company dedicates to produce and design step motor, DC brushless motor, and gearbox motor. Please contact us directly if you're interested.
