Quality Assurance Testing

Benshaw assembly teams perform a preliminary quality assurance inspection before delivery is made to functional test cells. Drive assemblies undergo a variety of testing procedures, including motor operation testing, load testing, control circuit testing, wire pull testing, electrical performance checks, mechanical alignment inspection, torque measurement and user interface/pilot device functionality.

All test procedures meet or exceed ISO 9001 requirements, and all tests are documented and archived for quality verification
