Sensored motor running without a lead

[4_cell_racer]

Ive had someone ask me if a sensored motor will run on a speedo (Mamba Max Pro) that will run sensored and sensorless motors, but wants to run it sensorless (without a sensor lead fitted)

Will the speedo run the sensored motor without a sensor lead attached?

Cheers

Yeah should be fine, the sensors are there for the benefit of the Speedo, not the motor.

Cheers for the quick reply Matt, great help

It can depend a little on the motor itself too. If the rotor is thin and/or the magnet is weak sensorless speedos can have trouble running the motor. This will be noticeable through excessive cogging.

Most are fine though so just give it a try. You won't be hurting anything.

The motor in question is a Orion Votex Pro race 7.5 if that helps?

Why does he want to run that motor sensorless may I ask?

when running sensoreless, the ESC will have a bit of a problem finding the neutral position of the Motor thus cogging is experience during start up, but when the motor is already running cogging issue is somehow lessens.
