Surface and form instruments are critical in the development and research of critical components of the NEV powertrain. Electric motors and power transmissions must perform to stringent engineering specifications to meet the demands of this newer automotive technology.
The common problem and issues present involve the reduction of noise and harshness that can be generated from electric motor assemblies and transmission gearing. Shaft and rotor form shape and gear tooth surfaces need closer analysis to prevent such noise in a quiet vehicle compared to internal combustion engines.
