    Z spindle motor has a constant torque below the rated power, and a constant power above the rated power. Therefore the starting torque is more stable comparing with normal induction motors. It also reduces a lot of unnecessary energy consumption due to directly start with an inverter. As the small inertia of the ac spindle motor, it is easy to start and stop, no carbon brush, no maintenance, no magnet, no need to regularly detect the magnetic pole position. Currently, it has been widely used in large starting torque or energy-saving industrial machines.
