1-Torque vs. current is linear and thermally limited to short duration. 2-Motor testing performed at 25 C ambient-no forced air cooling, with mounting heat sink of 3” x 0.375” x 8” aluminum. 3-Weight shown with wiring. 4-Magnet temperature stability limited. Tests performed using a 20-amp, 80 V dc trapezoidal BLDC PWM controllers with 50 H inductor each leg that adds .027 phase resistance. Input power includes driver and 50uH inductor losses.
