The Merits of the Permanent Magnet Stepper Motor

Permanent Magnet Stepper Motor's stator design is similar to the single-stack variable reluctance driver. The rotor is made up of permanent magnet poles made of high-retentive steel. It has a cylindrical shape. To form a two-phase winding on the stator, the concentrating windings connected to diametrically opposing poles are connected in series.

 

Permanent magnet stepper motors are highly compatible and efficient devices that have many applications. The rotor is made from permanent magnets and does not require external excitation. This makes it extremely useful for small motors, toys, and other applications. Its design allows for the easy creation of the step angle of each rotation. This makes it very useful in delicate applications like medical instruments and aeronautical structures. It is small and mobile, making it easy to use. This article will provide an overview of permanent magnet stepper motor.

 

Advantages and disadvantages of the PM Stepper Motor

Permanent magnet stepper motors offer many benefits.

Its compact size makes it ideal for many applications.

The losses are lower because there is no external excitation

The maintenance is lower because there is no external excitation.

It can be connected with the external circuit to control the speed.

To locate the rotor windings, sensors may be used

It can be used in a wide range speed and torque.

 

 

A permanent magnet stepper motor has the following disadvantages:
