Custom Molded Commutator The directional device acts as a rectifying function, and its function is to make the direction of the current in the armature winding alternating so as to ensure that the direction of the electromagnetic torque is always constant. Morotack commutator is made of high-quality trapezoidal copper (T2 copper or silver-plated copper) and molded with high-performance insulation. High mechanical performance, wear surface and stable operation. If you have special requirements, please contact our engineers, we will give you a satisfactory solution. We can proviede our customers for design and Custom.
