Phidgets Motor Control 1-Motor 1065_1B
Note: This version of the 1065 has a built-in heat sink for the driver chip to prevent overheating.
The 1065 allows you to control the direction, speed and acceleration of a DC motor. The motor is powered by an external power supply (9 to 28VDC).
Brushed DC motors are very simple to understand, but very difficult to control precisely. By applying a voltage or rapidly pulsing a voltage across the motor's terminals, current flows through the motor and it begins to rotate. Depending on the direction of the current, the motor will rotate clockwise or counterclockwise. The 1065 changes the effective voltage by changing the percentage of time the full supply voltage is applied to the motor. By switching the voltage very quickly (a technique called PWM), the controller becomes smaller, more efficient, and cheaper.
Rough control of the actual motor speed can be done automatically in software by using the back EMF property or current sensing.
Precise control of DC motors can be achieved by using encoders. Using the data provided by the digital inputs, analog inputs and encoder input, you can implement control loops in the software. There is an event that is triggered every 16 ms that returns the back EMF value for the connected motor, which can be very useful for PID control.
The 1065 also provides over-current, over-voltage and over-temperature protection to ensure that the board and motor are not damaged.
