What is a Permanent magnet stepper motor?<\/strong><\/p>\n\n\n\n

Permanent magnet stepper motors<\/a> are rotated using a magnetic core that interacts with the stator’s pulsed electromagnetic field.<\/p>\n\n\n\n

Two-phase permanent magnet step motors are usually two-phase. They have small torque and volume and a stepping angle of 7.5 to 15 degrees.\u00a0There are two parts to a motor: the stator and the rotor.\u00a0If the stator has a coil, then the rotor will be a permanent magnetic magnet. Or, the stator can be a coil and the rotor a coil.<\/p>\n\n\n\n

Principle of the Stepper Motor<\/strong><\/p>\n\n\n\n

The principle of operation of the stepper motor works in a similar way to a conventional motor. It operates on the principle known as Lorentz Force law. It states that a current-carrying conductor placed in a magnetic field experiences a force due to the interaction between fluxes.<\/p>\n\n\n\n

There are two types of flux that interact: stator magnetic flux (or rotor magnet flux).\u00a0External excitations create the stator magnetic flux, while permanent magnets create the rotor.\u00a0Fleming’s left hand rule governs the direction of motor.<\/p>\n\n\n\n

Advantages and disadvantages of the Stepper Motor<\/strong><\/p>\n\n\n\n

Permanent magnet stepper motors offer many benefits.<\/p>\n\n\n\n

Its compact size makes it ideal for many applications.<\/p>\n\n\n\n

The losses are lower because there is no external excitation<\/p>\n\n\n\n

The maintenance is lower because there is no external excitation.<\/p>\n\n\n\n

It can be connected with the external circuit to control the speed.<\/p>\n\n\n\n

To locate the rotor windings, sensors may be used<\/p>\n\n\n\n

It can be used in a wide range speed and torque.<\/p>\n\n\n\n

Precise Control<\/p>\n\n\n\n

A permanent magnet stepper motor has its disadvantages.<\/strong><\/p>\n\n\n\n

It cannot be used in high-power applications due to its limitations as a permanent magnet<\/p>\n\n\n\n

The amount of torque produced is very limited<\/p>\n\n\n\n

Permanent magnets have a limited life span.<\/p>\n\n\n\n

Applications<\/strong><\/p>\n\n\n\n

Permanent magnet stepper motors have many applications.<\/p>\n\n\n\n

Aeronautical industry<\/p>\n\n\n\n

Robotics<\/p>\n\n\n\n

Toys<\/p>\n\n\n\n

Manufacturing<\/p>\n\n\n\n

Control industry<\/p>\n\n\n\n

Printing and mills<\/p>\n\n\n\n
