If a small induction motor has a non-linear load, such as a fan, you can somewhat control … NettetThe permissible motor size for a direct-on-line start is dependent on the area of use. For example, there are power companies that no longer permit a direct-on-line start for motors rated 7.3 HP or higher. On the other hand, much larger motors are operated with direct-on-line start in industrial plants with independent supply systems.
Nettet11. jun. 2024 · Note that this speed control method works by weakening the motor so that the load forces the motor to operate at a reduced speed. If the load varies, the speed changes. If the load drops to zero, the motor goes to full speed. Without a load, there is no speed variation. Increasing the motor slip causes increased power to be lost in the … NettetMotor Starters and Protection.
