and decided to explore why wedge coils perform better than round coils in PCB motor designs. [atomic14]’s designs use four-layer PCBs which allow for more magnetic strength out of the coils made ...

Stepper motor drives can be classified based on the arrangement they are designed for. Unipolar drives are designed for unipolar motors, which are motors with 6 leads (center-tapped coils). Instead of ...

Some electrical coil winding machines are used in automated coil winding and assembly, magnet wire winding, transformer winding, or motor winding applications. Other coil winding equipment is used in ...

A research team led by Prof. Kim So-hee from the Department of Robotics and Mechanical Electronics, DGIST, has developed a ...

An electrostatic motor operates based on electrostatic forces, rather than the magnetic forces used by a standard electric motor.

This would tend to make the motor come to a stop, but two features allow the coil to continue rotating: This means that the current in the left hand part of the coil still causes a downward force ...
