What are variable frequency drives? What are AC motors?

Variable frequency drives (VFDs), or ac drives, are designed to reduce energy usage by controlling the speed of the motor and can offer cost-effective benefits for plants. AC motors convert electrical energy into mechanical rotating or linear energy to operate industrial equipment.
