Mid-drive motors

QS Motor QS138 70H mid-drive motor 3000 W

72 V, 52 N·m, IPM, IP67

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. #SPECS Motor type: IPM PMSM with hall sensors Rated voltage: 72 V Rated power: 3000 W Maximum torque: 52 N·m Pole pairs: 5 Magnet height: 70 mm Temperature sensor: KTY83-122 Insulation class: F Ingress protection: IP67 Cooling: Natural Output shaft: Splined, Ø20 mm, 6 keys Mounting: 6 × M8 on a Ø131 mm bolt circle, both ends Length: 197.8 mm Phase leads: 16 mm², 16-6 lugs (M6) Hall connector: DJ7061Y-2.3-11, 6-pin, sealed Lead length: approx. 650 mm Battery current, max: 150 A Weight: 10.5 kg #SPECSEND
