Can an electric motor take different voltages?

Just replacing the 24V pair of batteries with a 36V group will very likely cause something to fail. It is possible that a controller could be designed to allow a 36V group of batteries to work with the motor, but it isn't something that you are likely to be able to easily find and mate up to the existing motor. Additional information: If you get a 36V PWM controller and set the current limit to the maximum continuous rating of the motor, that might keep you out of trouble. If the motor has a higher short-time current rating that you want to utilize, that might be difficult to set up.
