Mechanical Dimension
Based on all these 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.
A BLDC motor takes the advantages from AC, DC and Universal motor types and combines them into one unit. It has the long life, low maintenance, quiet operation, and variable speed ability of an AC motor; the high starting torque and linear speed-torque curve of a DC motor; and like both AC & DC motors, it works well with gearboxes. Brushless DC motors have a high power density, second only to the Universal motor, and they have the best efficiency rating of 65 to 80 %.
