Let me start by saying pardon my ignorance on the topic. I have knowledge in electrical wiring but not so much in the technical engineering aspects of motors and micro-controllers.
I just purchased a Lincoln conveyor oven for a startup I'm working on. (They're are no electronics on the motor). The oven has a conveyor that has a slow and fast speed. I want to put a speed control on the motor to achieve a conveyor speed in between the two factory speeds. Basically set the motor to high and then have a separate control to slow down the motor (Not looking to double or triple motor speed).
This is the specs on the motor:
6 Wire harness to motor
Gry | Red | Blk ------------------------------ Brn | Wht | Wht
I've been digging around the internet but I wan't to make sure I'm doing this in the way that will ensure the full life of the equipment. I know voltage control is not a good method with a 3 phase motor. Any suggestion on how I could achieve the preferable with some type of rotary pot switch for granular control over the speed and no electronics.
Any help is greatly appreciated.
