A recent study, led by Runze Jing, summarized field weakening (FW) control strategies into calculation-based methods, voltage closed-loop control methods, and model predictive control-related methods.

Permanent magnet synchronous motors (PMSMs) are widely recognised for their efficiency and performance in applications ranging from electric vehicles to industrial machinery. However, the generation ...

Renesas’ RA8T2 motor control MCUs address real-time control in high-end factory automation and robotics applications.

Digital signal controllers enable drives for permanent magnet synchronous motors to be optimized with complex algorithms at low cost. When used in an appliance, a permanent magnet synchronous motor ...

There is a constant need and desire throughout the HVAC industry to spur innovation and create new products and ideas that can redefine the marketplace. In the realm of motors, the permanent magnet ...

When you think of electric motors, you usually think of magnets. But magnets are heavy, and good magnets can pose problems when you need lots of them. A technology called SESM (separately excited ...

Stepper motors are synchronous motors that step at the pulse rate of the driving signal. For the motor to move quickly, the stepping rate must be fast. However, because of motor and load inertia, the ...

Over the last 2 years [Carl Bujega] has made a name for himself with his PCB motor designs. His latest adventure is to turn it into a stepper motor by adding position control with microstepping. The ...
