| − | + | Generally motors are wired to a motor controller to provide speed control to motors. The motor controller can be used to change the directions of the motor as well. If running motors in parallel (as in a 4WD the two left and the two right motors will be running together in parallel) you can wire them in parallel too. | |
| + | |||
| + | Motor Controllers take signals from a microprocessor or radio control receiver and convert it into a high current varying voltage. Motor controllers are rated based on the voltage and current requirements. You can take a look at some of our robot kits to get an idea of what size motor controller you will need. We carry RoboteQ motor controllers, which will take encoder inputs for speed and/or position control, as well as Dimension Engineering's Sabertooth with a Kangaroo for encoder input. | ||

A motor controller takes a low current low voltage input signal and drives a motor with higher voltages and currents. The input signal can be serial, I2C, RC input, PWM, etc. Listed below are the many types of motor controllers with a brief explanation of each one. For full details of each motor controller go to the item page. Each motor controller item page has supporting links to data sheets, manuals, etc. | A motor controller takes a low current low voltage input signal and drives a motor with higher voltages and currents.

The output of a motor controller is PWM based, which stands for pulse width modulation. The concept of a PWM signal is to switch the output power on and off really fast in order to reduce the average voltage supplied to the motor in order to precisely control the speed of a motor. | The output of a motor controller is PWM based, which stands for pulse width modulation.

Generally motors are wired to a motor controller to provide speed control to motors. The motor controller can be used to change the directions of the motor as well. If running motors in parallel (as in a 4WD the two left and the two right motors will be running together in parallel) you can wire them in parallel too.
Motor Controllers take signals from a microprocessor or radio control receiver and convert it into a high current varying voltage. Motor controllers are rated based on the voltage and current requirements. You can take a look at some of our robot kits to get an idea of what size motor controller you will need. We carry RoboteQ motor controllers, which will take encoder inputs for speed and/or position control, as well as Dimension Engineering's Sabertooth with a Kangaroo for encoder input.
A motor controller takes a low current low voltage input signal and drives a motor with higher voltages and currents. The input signal can be serial, I2C, RC input, PWM, etc. Listed below are the many types of motor controllers with a brief explanation of each one. For full details of each motor controller go to the item page. Each motor controller item page has supporting links to data sheets, manuals, etc.

How a Motor Controller Works
The output of a motor controller is PWM based, which stands for pulse width modulation. The concept of a PWM signal is to switch the output power on and off really fast in order to reduce the average voltage supplied to the motor in order to precisely control the speed of a motor.
