42mm Slotless Brushless DC Motor

DINGS' Slotless Brushless DC Motor, 42ZWWC80 can avoid the pulsation of air gap magnetic induction caused by uneven magnetic resistance in the teeth.

It can eliminate the pulse loss in the armature core and the surface loss on the main pole surface.

42ZWWC80 Slotless Brushless DC Motor has high durability, low electrical noise and high efficiency.

Maximum efficiency of motor reaches 87.9% and this motor is suitable for the servo system which needs quick movement and high power.

42ZWWC80 Rated Power is 160W and Peak Torque is 3444.98mN.m.
