High Quality 24V High Speed Low Noise Hollow Cup Brushless Motor
Advantages of hollow cup brushless motor:
1. Energy saving characteristics: the energy conversion efficiency is very high, the maximum efficiency is generally more than 70%, and some products can reach more than 90% (iron core motor is generally 20-50%).
2. Control characteristics: rapid start and braking, extremely fast response, mechanical time constant less than 28 milliseconds, and some products can reach less than 1 milliseconds (iron core motors are generally more than 100 milliseconds); In the high-speed operation state in the recommended operation area, the speed can be adjusted sensitively and conveniently
3. The driving characteristics and operation stability are 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 hollow cup motor is greatly improved, and its weight and volume are reduced by 1 / 3-1 / 2 compared with iron core motor with the same power.
