JSUMO Core DC Motor 6V 750 RPM

The speed-biased sibling of our best-selling Core motor line. Same 15mm-diameter brushed gearmotor platform as the Core 400, geared for higher RPM instead of maximum torque. A good choice if your bot relies more on ring speed and repositioning than raw pushing power, or as a second-motor option to compare against the 400 on your own bot.

400 vs 750 — which one? In a 500g bot with no magnets, wheel traction limits how much stall torque you can actually put to the ground — both motors have far more stall torque than a typical silicone tire can transmit. Pushing-contest and wedge-lock strategies generally favor the 400 (more torque margin, less current draw per unit of push, runs cooler in a stall); the 750 suits builds prioritizing repositioning speed and ring coverage. Same 3mm shaft, same mounting footprint, so many builders stock both and pick per-match.

Works with:

• Wheels (3mm bore, direct fit): JS2622 Aluminum, JS2622S Steel, SLT20 Aluminum, SLT20P Steel
• Start module (required at most tournaments): JSUMO MicroStart
• Sensors: JS40F opponent sensor, Lunox Line Sensor / ML1 for edge detection
• Torque-biased alternative: Core DC 400 RPM

Driver sizing note: at 3S/4S this motor can pull 6–10A at stall — size your motor driver's per-channel peak rating above that, per motor. Small breakout drivers rated ~1–3A are not sufficient for main drive duty.
