The video seems to stop prematurely around 2/3 of the video on my laptop for some reason so just click on the tracker bar to watch the rest of it. •The Basic PWM Control. SMART 2010. Stepper Motor. •Do not spin freely with just power. •Driven by the interaction (attraction and repulsion) of magnetic fields. •With proper sequence of the on-off pattern of the magnetic fields, the stepper turns (when it’s not, the stepper sits and quivers). SMART 2010. •Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver. (More generally, rewiring anything while it is powered is asking for trouble.) Step (and microstep) Size: Stepper motors typically have a step size specification (e.g. 1.8 or 200 steps per revolution), which applies to full steps.

    Stepper motors are used for accurate positional control. They require an external controller such as a dspic to operate. By magnetising the different windings in a certain order you can organise the stepper to move in any combination of directions.

STEPPER MOTOR THEORY. Motors convert electrical energy into mechanical energy. A stepper motor converts electrical pulses into specific rotational movements. The movement created by each pulse is precise and repeatable, which is why stepper motors are so effective for positioning applications.

The output torque and power from a Stepper motor are functions of the motor size, motor heat sinking, working duty cycle, motor winding, and the type of driver used. If a stepper motor is operated no load over the entire frequency range, one or more natural oscillating resonance points may be detected, either audibly or by vibration sensors.

An A4988 stepper motor driver is a great way to drive stepper motors. It requires a digital pulse signal to run the stepper motor for consecutive steps. It also features a micro-stepping function. The RPM of the stepper motor depends upon the frequency and duty-cycle of the input pulses. In this project, I will be showing you how you can make a simple stepper motor controller by using a 555 ... In this example a short push turns on led2 and a long push turns it off. It also does software debouncing. The encoder driver assumes that its input connections are debounced in hardware and has cw and ccw actions. In this example a cw turn of the encoder increases the flashing led1 duty cycle, and a ccw turn decreases the duty cycle.
