Coming in 2- and 4-pole designs with or without hall sensors, Koford Engineering’s new line of 36 mm slotless brushless motors achieve efficiencies of up to 89%. The instruments present power outputs from 10 W to 620 W, speeds from 3,600 rpm to 30,000 rpm, and mechanical time constants as low as 4 ms. The 4-pole configuration doubles the resolution for hall feedback speed control. The cog-less motors are engineered to provide a straight line speed torque relationship under all conditions. Optional gearboxes and encoder, integral 2- or 3-wire electronics, and matching hall and sensorless drives are available.
