Focussing on both single and multiturn NUM encoder types, our system allows us to scan your motor’s electronic nameplate to ascertain the exact requirements needed for repair. If your motor’s nameplate is corrupted, the team at Alpha Electrics can reprogram the encoder’s electronic nameplate, a process that allows us to guarantee the accuracy and success of our repair.
