I am building a robot using your 12volt wiper motors. I would like to know what speed controllers you recommend I use. I'm controlling the robot using remote control rather than radio control. |

Giles, You say remote control but not radio control. It would assist if you could advise the form of remote control. Electronize speed controllers work on a 1 to 2mS pulse signal as found on radio control receivers. Many customers have used Electronize controllers on non-RC set-ups by emulating this pulse signal. Our H Bridge controllers offer 3 types of signal input, RC (1-2mS), voltage (or pot) or I2C as found on many microcontrollers including on many PIC's. The wiper motor we sell has a current in the range of 2-6A approx and does depend on load and speed selected. However, for robots, you should size the speed controller based on the stall current of the motor. We have not tested the stall current of these motors but would guess at 25 - 35A. There are other considerations but we know that many customers have used the Electronize 15A CPU version and the 30A with external relays versions with success. Alternatively, we also know that the 5A H Bridge has also been used but would recommend the 20A version as the preferred option. |

Do you know the amperage of the fiat wiper motors? Thanks. |

Giles, not exactly sure but is most likely in the range of 2-6A |

I have a question about you windscreen wiper motors. I would like to know how much weight they would be able to manouve.I am trying to turn a weight of 15kg and didn't know whether the motor would be able to support this and rotate it. |

We do not have any figures of the torque output of these motors. It would also depend on how far away from the centre of the motor output shaft the 15kg weight is distributed. We are aware of some customers rotating quite heavy weights with these Ww motors but we do not have any firm facts on this. |
