Motor Hall Sensor 41F on 60 degree PCB (NAMI Burn-e etc)

• 41F hall sensors are a common sensor used on eScooter motors, such as NAMI Burn-e 1500w motors.
• Hall sensors are responsible for wheel positioning (rotation / speed). They typically have 5 relatively thin wires that ultimately lead to the controller. If there is a fault with hall signalling, errors are thrown (such as 201 rear / 202 front motor error on NAMI systems) or throttle may cut out unexpectedly. Often they can be intermittent and get worse as the sensors degrade. It is not recommended to "ride through" errors, as the positioning plays an important roll high current switching (and stress on controller).
• Supplied as three 41F sensors (which are the most commonly used amongst eScooters) factory fitted on PCB with the 5 flylead wires (as shown). Order quantity two (2) for both front and rear wheels.
• Often sensors are cut from the PCB and retrofitted to existing hall sensor PCB and/or cut to modify the length for appropriate placement. PCB's are not universal / common amongst motors, each motor typically has it's own custom-shaped board. eSN supplies the complete board (PCB) as reference.

Notes:

1. The 41F is understood to be "drop in replacement" in NAMI Motors, however the reports do not indicate if the halls themselves are dropped in (retrofitted), or the entire PCB assembly is "drop in replacement". eSN understands the former is the case, feedback is welcome.
2. You typically clean out the motor (rust etc), assess bearings and fit new seals (e.g. NAMI) when renewing halls.
