Abstract: This paper proposes a new PWM switching method, called copolar switching, for synchronous rectification in brushless DC motors (BLDC). This method-integrates the benefits of both unipolar ...

Abstract: Brushless DC (BLDC) motors are increasingly being used in a wide range of applications due to their superior characteristics such as reliability, high efficiency, high torque-to-weight ratio ...

The simulation hypothesis—the idea that our universe might be an artificial construct running on some advanced alien computer—has long captured the public imagination. Yet most arguments about it rest ...

You cannot remove the brake system in fact. The regenerative brake force of an electric motor is proportional to motor rpm so at low speeds the brake force is almost zero. Click to expand... You can ...

One of the big stories of last year’s Consumer Electronics Show in Las Vegas was the debut of Donut Lab’s diminutive but powerful electric motors. When I spoke with Donut earlier this year, the ...
