Electric Motors

Discussion in 'General Motoring' started by Stewart Hargrave, Mar 18, 2005.

  1. How many electric motors does your car have? My '87 740 has 27
    (unless I can think of any more). Higher spec., newer cars should
    easily be able to exceed this.

    1 x starter motor
    1 x windscreen wiper
    1 x rear screen wiper
    2 x headlight wipers
    2 x screen wash bottle (front and rear)
    1 x radio aerial
    1 x cassette player
    4 x window motors
    5 x door/tailgate lock motors
    1 x heater blower
    4 x door mirror motors (2 in each)
    2 x fuel pumps
    1 x electric clock
    1 x LPG/petrol actuator (as per conversion to LPG)

    Sometime soon I may be fitting one to the sunroof. I've not counted
    the speedo or rev counter, though I suppose these could be included on
    a technicality.

    Idle control valve on mine is a true DC motor.

    Don't overlook the motor that drives your odometer...

    Some of those 'motors' on your list may not be motors. I think one or two of
    them may be solinoids instead, mainly the Locks (unless you have one of
    those trunks that latch partly open then pull it the rest of the way
    closed), and the LP actuator might be one as well. (many are solinoids)

    Door/locks are solenoids,
    3 seat motors in my driver seat
    1 sunroof motor
    2 radiator fans

  8. Motors are motors in all cases. Solenoids not counted.

  9. Are you sure about this? I'm surprised that your 940 should be
    different to my 740 on this detail.

  10. 28.

    I'm thinking that a high spec. car with 3 way electric seats, interior
    mirror, convertable roof, self closing doors, DVD player, and any
    number of other things, may be able to exceed 50.

    The heat control valve and air distrubution are both controlled by motors on
    modern cars, not sure about how many.

    I seem to recall reading somewhere that the new Phaeton (VW) and Maybach
    (Mercedes) have over 100 individual motors each :)

    ....... and probably way more computer power then most people had access to
    in the mid 90's

    The "lock motors" on my 740 are solenoids as well, there's two of them that
    pull in on opposing sides of a lever, it's all one assembly and is
    technically a motor as is any other solenoid, they convert electrical energy
    into mechanical motion, solenoid is simply a subclass.

  15. OK. My experience is only with units that have little motors in them,
    as fitted to my current 740, and some earlier 200s
    FFS, it was just an mildly amusing distraction that I idled away a
    traffic jam with. I wasn't hoping for an exposition of subtle points
    of definition.

    Jeez... Volvo owners, eh?

    The only thing is, the more of them you have, the more there are to go
