1. A unit for recording operating information of an electric motor, said unit comprising:
- a motor controller communicatively coupled to an electric motor, said motor controller comprising a processing device configured to control said unit, collect operating data from an electric motor, and identify when a change in operating conditions of the electric motor occurs;
a memory device communicatively coupled to said processing device, said memory device configured to receive and store motor operating information in response to identifying the change in operating conditions of the electric motor; and
a voltage limiting circuit coupled to said memory device, wherein said voltage limiting circuit protects said memory device from an over voltage condition caused by the change in operating conditions.
