Abstract:
A method may include receiving, via a processor, a request to enable movement of a rotor. The method may involve sending a first signal to a mechanical relay system in response to receiving the request, such that the second signal may cause a mechanical relay to close. The mechanical relay system is configured to couple a first conductor to an EM brake. The method may also include sending a second signal to a solid-state relay system after sending the first signal to the mechanical relay system, such that the second signal may cause a solid-state relay to close. The solid-state relay system may couple a second conductor to the EM brake, such that the EM brake may open after receiving power via the first conductor and the second conductor.
