BLDC motors
Flat external rotor for tight installation spaces
With the DFA90, Nanotec is expanding its range of BLDC motors with an external rotor with a rated power of up to 170 watts and a diameter of 90 millimeters.
The DFA90 is available with two different windings for 24 volts and 48 volts and is equipped with digital Hall sensors for simple control. Customized windings or shaft modifications are also possible. The maximum rated speed of the DFA90 is 2,720 revolutions per minute and its rated torque is 0.96 Newton meters.
Nanotec has also added the DFA68, an external rotor with a diameter of 68 millimetres and a rated output of 110 watts, to its range. A housing with protection class IP54 protects the rotor of this motor against the ingress of splash water and foreign bodies. The DFA68 is designed for a rated voltage of 24 volts and achieves a rated speed of 3,700 revolutions per minute and a rated torque of 0.29 Ncm. Its 14-pole design ensures smooth running at low speeds.
The new external rotor motors from Nanotec are suitable for use in applications with limited space, such as access control systems or belt drives. as
