    Check this out on flea bay


    Supply Voltage: 8 to 48 Volts DC
    Load Current: 80 AMPS Continuously, with Resistance and Inductive loads
    120 AMPS for short periods of acceleration (up to 10 sec.)
    Range of regulation: PWM 0 to 100% of power
    Overheating protection: When the module is overloaded, power is automatically
    decreased, in order to protect mosfets from destructio

    I wonder if this would work to control the motor speed for electric motors for spreaders has any one ever tried one?

    Considering the prices I seen for DC motor controllers when we were looking for one, that is way cheap - I would of tried it for what we were doing, contolling a single function on a cheap motor.

    It seems like wicked vodoo to just simply control the voltage to a DC motor for a simple salt spreader - I shoulda stayed in school and got that EE degree.

    You need to PWM the signal, if you rely solely upon a resistor the heat in the controller would destroy even a steel housing.

    MOSFETs are a prime way of doing this, and honestly it looks to be a well done setup.

    Might hafta try one out.
