Unidentifiable motor


I took this motor out of a BMW E90, and I can't seem to find it on the internet. It seems to be manufactured by Johnson Electric. It was used to operate the steering lock in the vehicle. I also don't know if there is a specific name for such a motor; it has a location for plugging in instead of strips or wires. I'm trying to find it's specs and the model number in order to find and purchase it. I think the pic has the model number, but I haven't been able to find it using that number. It's design seems useful for certain applications.


I’m trying to figure out what kind of motor I have here. It has Johnson stamped on one side where the brass gear is located, so I am assuming it’s produced by Johnson Electric. It was taken out of a BMW E90, from the steering lock. I am trying to find it’s specs and a place to buy them. It’s design seems useful for certain projects. Instead of strips or wires, it has a female plug end for connecting to current.

It looks like an extremely common motor. I'm sure you can get very similar (but not identical) ones from China for under a dollar.

  • You may know what an E90 is, but I don't. I think it might be a car but it could easily be a motorcycle or a boat motor.

Is that what is often referred to as a 130 motor. This Mabuchi website explains the nomenclature for their motors and as far as I can see many (most) of the small motors are physically similar to one or other of these. What is inside them is a different matter, of course.


Presumably its a 12V DC brushed motor. You could measure the stall current (or equivalently the
winding resistance). Typicall small motors run continuously at 10 to 20% of the stall current -
the limiting factor is always overheating. The size of the motor is strongly correlated to the
heat it can dissipate.
