4 wire motor and high high can voltage go?

<P style="MARGIN: 0px">How should I hook-up four wire motors to get direction and speed control? Another post was a bit confusing.

<P style="MARGIN: 0px">Using 36 volt motors and the new 3500 controller. The controller is going to get voltage excursions higher than 40 volts from the batteries.

<P style="MARGIN: 0px">Is this a problem? Should I use some other product, clamp the voltage the controller see's, or just not design with 36 volt motors?

<P style="MARGIN: 0px">The motor voltage is not an issue. The battery voltage is. The controller will work with 36V batteries. It is rated at 40V but it's overvoltage protection circuit triggers at 43, which should be fine, even with fully charged batteries.
