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.

MUNICH, Germany—ZF unveiled an electric motor that does not require magnets or rare earth materials, reducing reliance on mining in countries such as China and cutting manufacturing's carbon footprint ...

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 ...

Changing the orientation of rotor magnets on the fly lets a special kind of induction motor run directly from ac lines. The quest for energy efficient electric motors has generated a lot of ...

Microprocessor control lets variable-speed PMSMs save energy. Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, ...

I2SM does not require any brush elements or slip rings. ZF has developed a magnet-free electric motor disparate to Separately excited synchronous motors. The motor is compact with maximum power and ...

The power of a synchronous motor depends directly on the load angle: the greater the load angle, the more torque, which determines the power by the speed specified by the input gear and the ...

Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use ...
