Slotless DC Brushless Motors

Motion Control Products has introduced a new range of precision slotless DC brushless motors. These offer several advantages over conventional DC motors, including longer life expectancy, lightweight design, and reduced vibration and noise. Additionally, they exhibit minimal cogging even at very low speeds.

Slotless motors are engineered for smoothness and predictable torque output. By placing only copper phase coils in the motor's air gap, they interact with permanent magnetic flux to generate force or torque. This design eliminates cogging torque by removing discontinuous iron teeth from the motor air gap. Slotless technology is especially effective for direct drive precision systems, as torque is solely a function of phase current, minimising unwanted torque disturbances.
