Testing Systems for Servo Motors A Servo Motor is a closed-loop servomechanism that uses position feedback (like encoder) to control its motion and final position. The input to its control is a signal (either analog or digital) representing the position commanded for the output shaft. Servo Motors are used in radio-controlled airplanes to position control surfaces like elevators, rudders, walking a robot, or operating grippers. Advantages • Excel at position and speed control. • High output power relative to motor size and weight. • Encoder determines accuracy and resolution. • High efficiency. It can approach 90% at light loads. • High torque to inertia ratio. Servo Motors can rapidly accelerate loads. • Achieve high speeds at high torque values. • Quiet at high speeds. Disadvantages • Requires tuning to stabilize the feedback loop. • Will become unpredictable when something breaks, so safety circuits are required. • Complex controller requires encoder and electronic support. • Peak torque is limited to a 1% duty cycle. Servo Motors can be damaged by sustained overload. • Gear boxes are often required to deliver power at higher speeds. • Higher overall system cost and the installation cost of a Servo Motor system may be higher than that of a stepper motor due to the requirement for feedback components. Maximizing Precision Leveraging Motomea for Servo Motor Testing The Motomea Regenerative Dynamometer System (Motomea RDS) enables: • Complete load performance testing: Torque, Speed, Current, Efficiency, Power Input, Power Output. • Standard electrical parameters testing: HV, Vibration, Noise, and others.
