What are the benefits of adding encoders to stepper motor?

Today’s complex projects, such as quadcopters, often call for enhanced position control. Stepper motors have been developed to deliver excellent precision, allowing very predictable performance when the step angle and gearbox ratio are both known.

But even with the great visibility into position and velocity that a stepper motor offers, some engineers have taken things a step further.

Not content with the stepper's native open loop control, they’ve added encoders to their motor systems.

Motion controller brand Galil conducted a series of side by side tests between open and closed loop stepper motor systems. Their team discovered that the addition of an encoder could produce appreciable gains in major performance metrics.

Compared to the open loop system, the closed loop system offered:

Significantly improved velocity smoothness;

Reduced overall current consumption;

Higher torque at lower velocities than comparable three-phase brushless servo motors.
