A new brushless, slotless motor from Koford Engineering LLC features high speeds to 104,297 rpm with 94% peak efficiency with 980 W of power in a 42-mm diameter. Available with either hall sensors or sensorless, it features custom ceramic hybrid bearings with machined Torlon retainers. The slotless construction is free of cogging and nickel-iron laminations are used for low losses. A winding temperature sensor is also available.
The motor has a hardened and precision ground 440C shaft and uses Teflon-insulated 200C rated lead wires. The operating voltage is 48V DC, and a matching hall and sensorless drive with a speed pot or 0-5 V control inputs are also available.
