Hollow cup motors mainly include

• 1. Energy saving characteristics: The energy conversion efficiency is very high, and its maximum efficiency is generally above 70%. Some products can reach over 90% (iron core motors are generally above 70%).

• 2. Control characteristics: fast starting and braking, extremely fast response, mechanical time constant less than 28 milliseconds, and some products can reach up to 10 milliseconds (iron core motors are generally above 100 milliseconds); It is convenient to adjust the speed sensitively during high-speed operation within the recommended operating area.

• 3. Dragging characteristics: The running stability is very reliable, and the speed fluctuation is very small. As a micro motor, its speed fluctuation can be easily controlled within 2%. In addition, the energy density of the hollow cup motor has significantly increased, and compared with iron core motors of the same power, its weight and volume have been reduced by 1/3 to 1/2
