Topics covered in this video: circuits, current, magnets, electromagnets, armature, commutator, brushes, stator, and rotor. This video only covers DC motors. Maybe I will cover AC motors in a ...

Stepper motors and servomotors both belong to a class of motors designed for precise position control. Steppe r motors are brushless DC motors that move a rotor in small angular steps or fractions of ...

In every brushless DC motor, there are a few common parts: the rotor has a few powerful magnets embedded in it, a stators with coils of wire, and the an enclosure to keep everything together.

The torque constant and the torque produced by the rotor allow us to calculate the current through the armature, which is used to calculate temperature ratings (as shown later). Design Tip: DC ...

[Levi] whipped up his brushless DC motor design in OnShape. The motor has six coils in the stator, with the rotor carrying eight neodymium magnets. It’s an axial flux design, with the rotor’s ...
