New high power density 40 mm brushless motors

Koford Engineering LLC has introduced a line of outer rotor 40mm diameter brushless motors with exceptional power to weight and size. Weighing only 203 grams they provide a peak output of 900 watts and a continuous output without external cooling or heatsinking of 499 watts. Available input voltages range from 12v to 48 volts and no load rpm from 3,100 to 12,400. Peak efficiency is up to 89%. Matching drives with speed pot or 0-5v control inputs are also available.

Motor Data

Ambient temperature range -73°C to 149°C. Weight 7 oz. (203 grams), maximum winding temp. 180°C. Continuous motor power must be reduced. Contact factory for more information. Data is for winding and magnet temperature of 20°C. For 12 amp drive peak power is limited by drive current limit. Phase leads are 18 AWG.
