After testing dozens of cordless leaf blowers, we've found the perfect combination of power, usability and affordability. Cordless leaf blowers are a garage staple, tackling grass, leaves, and even ...

A nonlinear control scheme is proposed for real-time tracking of maximum torque per ampere trajectory of the surface-mounted brushless dc motor with non-sinusoidal back electromotive force (back-EMF).

In this paper, the principles of motor torque and suspension force generation in bearingless brushless motors with high pole numbers are explained, graphically illustrated, and analyzed in detail. The ...
