Unlike their brushed relatives, BLDC motors rely on external controllers to achieve commutation. Put simply, commutation is the process of switching the current in the motor
Websimple analytical techniques that can be used to understand the operation of a BLDC motor. The case study is our Razor scooter hub motor, a BLDC motor designed inside a 5” diameter wheel. Fundamental Physics Electric motors transform power from the electrical domain to the mechanical domain using magnetic interaction. Web1. The motor will have either three or four leads. If there are four, the winding configuration is almost surely a "Y" or "wye" configuration and one of the leads is the center-point. If you have the four-lead variety, identify the center-point by measuring the resistance between the …
