This white paper details a lab comparison of closed loop stepper motor systems vs. traditional open loop systems. The test monitors power consumption of both motors when turning a dynamometer at a fixed speed of 10 rev/sec (600 rpm). Results show that closed loop systems offer greater motor efficiency, cooler operations and lower energy consumption for greater operational savings.
