Pittman slotless brushless motor designs offer many advantages over conventional slotted stator construction. Negligible magnetic cogging provides improved servo performance and enables extremely smooth motion even at low speeds. Low inductance and high current bandwidth results in fast move response times. The slotless construction also provides excellent winding heat transfer for high thermal efficiency and transient load capacity. The slotless brushless dc motor designs have internal Hall Effect feedback sensors for linear speed-torque characteristics, high starting torque, and variable speed control when used with the appropriate drive electronics.
