High positioning accuracy and repeatability: minimal error per step; repeatable micron-level positioning; no encoder required; low cost
Fast response and excellent dynamic performance: direct drive of load; no transmission delay; fast acceleration; suitable for frequent starts and stops
Simple open-loop control system: frequency control of speed; no closed-loop feedback device required
High torque at low speeds with direct drive: High torque output at low speeds; capable of directly driving loads; energy-efficient and maintains stability when stationary
