I am trying to locate a replacement N30 size 6V 330 rpm gear motor for a RC Model retract. The motor controller senses the stall current at the up/down end points to turn off the drive voltage of nominally 6V. I have measured the controller stall current trip point and it is about 1.7 Amps
What I measure from the remaining good one:
Free run current, no load: 170mA @ 6V
Run rpm: 330 RPM
Run volts: 6V
Nominal operating current with the gear moving: 400mA
Stall current is estimated @ >= 2 amps
DC resistance: 1.4 ohms
Physical characteristics: N30 gear motor with 3mm D shaft. (5mm)
Same diameter as the Pololu N20 micro gear motors but longer.
The nearest Pololu gear motor I can identify is the smaller N20 HP6V 100:1 Micro Metal Gearmotor : Pololu item # 1101
The DC resistance is not included in the Specifications. I suspect it is not low enough to meet the controller current trip point limits reliably.
Also as is a smaller motor may not have the same torque.
Does Pololu offer a gear motor in the N30 physical configuration that would meet my needs ?
Or can you perhaps recommend an alternative.
