Description
Coil of high precision with a unique design, free of iron core
Rare earth magnets of high performance, with high power density
High torque, efficiency, and low noise, with a stable service life
Operation is smooth and response is rapid
Low temperature rise ensures motor stability
The 22D X 25L DC Coreless Motor 12V, 11500 RPM has outstanding characteristics of energy saving, control and driving, mainly including:
1. Energy saving characteristics: the energy conversion efficiency is very high, its working efficiency is generally more than 70%, and some products can reach more than 90% (iron core motors are generally 20-50%).
2. Control characteristics: rapid starting and braking, extremely fast response, mechanical time constant less than 28 milliseconds, and some products can reach less than 10 milliseconds (iron core motors are generally more than 100 milliseconds); under the high speed operation condition in the recommended operation area, the speed can be adjusted sensitively and conveniently.
3. Driving characteristics: the operation stability is very reliable, and the fluctuation of speed is very small. As a micro motor, its speed fluctuation can be easily controlled within 2%.
In addition, the energy density of the coreless motor has been greatly improved, and its weight and volume are reduced by one third to one half compared to an iron core motor of the same power.
All the technical features of this product series developed by our company have reached the same level as those of Maxon and Faulhaber. It is widely used in medical treatment, testing, handheld instruments, intelligent robots, precision automation, aerospace, extreme temperature instruments, industrial and mining operation equipment, and other industries.
