The plastic extruder used permanent magnet synchronous motors

Multi-Pole Permanent Magnet Direct Drive Motor

The more poles of the motor, the slower the maximum speed of the motor. This new type of motor is to control the speed of the motor below 100rpm by increasing the number of poles of the motor, and we customizes the motor directly connected to the screw according to the size of the extruder screw and barrel flange. With this kind of multi-pole motor, the extruder will no longer need gearboxes, couplings, pulleys, and other devices, which greatly simplifies the structure of the plastic extruder and saves the maintenance of these parts, and also greatly reduces the equipment performance. It can save more than 30% of electrical energy than DC motors and 15% of electrical energy than AC asynchronous motors. It can also achieve step-less speed regulation to meet the requirements of different process products.
