Matrix E-blocks2 Actuators Board BL0127

Description

The E-blocks Actuators board allows for investigation into several different motor types - a DC motor, a servo motor and a stepper motor.

Included on the E-blocks2 Actuators board is a DC motor with both analogue and digital feedback, a servo motor and a stepper motor plus the circuitry to drive the motors.

The DC motor is driven using a standard H-Bridge driver IC and can be driven using simple digital on/off right through to analogue pulse width modulation (PWM) techniques. By monitoring the feedback, a closed loop control system can be made to control the speed of the motor. A second H-Bridge driver IC is used to drive the four coils of the stepper motor allowing for full step and half step operation. The stepper motor features an internal gearbox to provide a high level of torque and precise angle control. The servo motor is a standard R/C servo motor with a supplied actuator arm.

The board features a DC socket to allow the various drivers to be powered from a secondary power supply.
