Koford Engineering LLC has introduced a line of 24 V and 48 V 4 pole long stack 60 mm diameter slotless brushless motors with a 1,646 watt output at 14,685 rpm at 48 volts. The peak motor efficiency is 93 percent. The 24 volt version outputs 784 watts at 6,855 rpm and has a peak efficiency of 92 percent. The motor weighs 1.47 kg. These motors are offered in hall sensor and sensorless versions, and also the option of a temperature sensor. The slotless design offers exceptional efficiency and power density with zero cog and linear torque behavior which is ideal for servo applications.
