DINGS' Slotless Brushless DC Motor, 16ZWWC40 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.
16ZWWC40 Slotless Brushless DC Motor has high durability, low electrical noise and high efficiency.
Maximum efficiency of motor reaches 85% and this motor is suitable for the servo system which needs quick movement and high power.
16ZWWC40 Rated Power is 39W and Peak Torque is 118.13mN.m.
In a mobile environment, you can move left and right to see the contents (tables).
