Another motor speed controller? This one is a little bit different and offers boutique performance in the world of speed controllers. While the simpler circuit of our other motor controller kit (KC-5477) will control a motor's speed fairly well, it can't provide maximum speed as the output voltage is limited to about 160VAC maximum. It also doesn't provide great speed regulation and torque at low speeds. The deluxe kit addresses all these issues and provides full speed control from near zero to maximum RPM, good speed regulation under load, very smooth low speed operation and is rated for devices up to 2300W. It also has soft-start to eliminate the kick from larger power tools and has interference suppression filtering, fuse protection and over-current protection with limiting. This kit really is the duck's guts for motor speed control. The case has the tricky cutouts pre-machined, but a little bit of extra drilling is required to complete the project.
* Overlay PCB and all components.
* Machined case included
Note: This project is designed for brush type motors and is not suitable for induction motors or shaded pole motors.
Note: Not for use with induction motors. See KC-5509 for controlling induction motors.
