EMP contactless controller
2x over-excitation
The EMP controller is a contactless controller used for electromagnetic clutches/brakes. It uses a 2x over-excitation method and a time lag circuit to achieve very stable operation even when high frequency and high precision is required. Additionally, it uses a fully contactless technique circuit configuration utilizing power transformers, yielding high performance and long operating life.
