The primary feature of stepper motors is listed right within their name: their ability to ‘step’ forwards and backwards, something which they (ideally) can do perfectly in sync with the… ...

Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By ...

Global Permanent Magnet Motor Market to Reach $39.1 ... different techniques are used to produce and control magnetic fields. Brushless DC motors are generally used in appliances and other low ...

Permanent magnet, permanent power transmission Aug. 1, 2004 When frequent disengagement wears too heavily on mechanical couplings, magnetic designs transmit power without the physical contact that ...

When power is first applied, the permanent magnet in the rotor of the stepmotor aligns with the magnetic fields generated by the windings. To step the motor, current in one phase is turned off.

US patent 382,279 Electro magnetic motor – Figure 1. And speaking of Nikola Tesla, he claims to have thought of the idea of the rotating magnetic field one afternoon in 1882 while walking in a park.

In the realm of motors, the permanent magnet synchronous motor (PMSM) is a relatively obscure option that is gaining significant traction in the space. The overall global electric motor market was ...

DC synchronous motors need a direct current supply for the rotor to generate a magnetic field. These motors have both stator-winding as well as rotor-winding and are found ... Servo motors are ...

The difference is that a permanent magnet motor adds permanent magnets—magnets typically made of rare earth metals that have their own permanent electromagnetic field—to the rotors in a motor.
