A recent customer asked if it were possible to connect a motor to both channels to increase the maximum amount of current. For example, with the Sabertooth Dual 60A (TE-091-260), whether or not it would be possible to get 120A out of it.
The answer is no. Doing so will permanently damage the motor. Motor controllers use a circuit topology called an H-Bridge. Each motor terminal is connected to your battery power and ground through a transistor. The output voltage that controls the speed of the motor is achieved by throttling these transistors in a pattern using a series of PWM signals. Connecting a motor to the center of two H-Bridges will cause an event where a motor is both connected to your battery and ground at the same time. This will cause a surge of current through the H-Bridge which will destroy the circuit.
This is a great clarification. However, If we wanted to attach two 12v linear actuators to a single controller, would that be possible. We would like these two actuators to act as one and move in unison without controlling each seperately.
Daniel,
You should have no issue doing that.
