Interior permanent-magnet mid-drive motor (IPM PMSM) from QS Motor for 72 V. Rated power is 3000 W and maximum torque 52 N·m according to the manufacturer's test. The motor has hall sensors and a temperature sensor (KTY83-122), is sealed to IP67 and is naturally cooled. The output shaft is splined (Ø20 mm, 6 keys) for a sprocket or belt pulley. The motor mounts with six M8 threads on a 131 mm bolt circle at both ends. The phase leads (16 mm²) have M6 lugs and run in an orange protective sleeve. The hall connector is a sealed 6-pin DJ7061Y-2.3 plug that mates the hall plug on the Fardriver ND-series harness. The controller must limit battery current to 150 A or less, for example a Fardriver ND72450 with an adjusted current limit. Sprockets and belt pulleys for the motor are sold separately.
