Low Noise 24 V Brushless Dc Moto Factory Supplyr NEMA23 1.8 OHMS 57mm*57mm 42BLF05A
These brushless DC motors use efficient ceramic ferrite permanent magnets bonded to the rotor to produce the magnetic field. Thus, there are no losses in the motor due to rotor induction currents. All of the current delivered to the brushless DC motor is used to develop torque.
The powerful and lightweight permanent magnet rotor design provides low rotor inertia for high torque to inertia ratios in a relatively small frame. This high torque density equates to a very responsive motor with high starting and running torque, rapid start-stop capabilities and smooth operation over the entire speed range.
