Description
Hollow Cup Motor (CF-BL2845)
Cifu Technology manufactures a series of high-performance brushless coreless DC motors that combine high efficiency, stable output, and long service life. Available in a wide range of voltages and configurations—and compatible with gearboxes, encoders, and other accessories—these motors provide reliable power solutions for automation equipment, robotics, and intelligent control systems.
Note: Motor data is measured in a standard test environment at 25°C. Operating the motor beyond the recommended continuous maximum parameters may reduce its service life or cause damage. In high-temperature environments, the load current must be reduced to protect the motor.
Naming Convention
e.g.
CF-BL2850
Meaning:
* CF = Cifu
* BL = Brushless
* 28 = Outer diameter 28mm
