Stepper motors are useful in many consumer, industrial, and military applications. Some, such as personal-transportation systems, require precise speed control. Stepper-motor controllers can be simple ...

Figure 3-5: Stepper motor control circuit. This project uses the ULN2803 octal high-voltage, high-current Darlington array to switch the stepper coils. This chip is readily available for around $0.75 ...

The Easy Stepper Motor Controller is a very simple board with connections to a motor, a power supply, and headers for a single Pololu or Stepstick motor driver.

Stepper motors generally include a motor, drive, and controller. The motor, a brushless dc version, moves in equally sized fixed steps during rotation, and only rotates one step at time. Stepper ...

When you write software to control a stepper motor, you must first know how many pulses the motor needs to turn a full rotation. In addition, you need the rotational speed expected by the device ...

It uses simple logic circuitry and application software to control selection of the stepper motors, their clockwise or counter-clockwise motion, and the step size: full step, half step, or microstep.

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

A stepper motor controller/driver IC integrates a digital control core which enables a single microcontroller to easily manage several motors, because it only has to issue high-level movement ...

AutomationDirect has added the new Titanio series of stepper drives from Ever Motion Solutions that work with ...

It is small, at 1.6 inches (40 mm) square, and provides up to 2 amps drive current for one axis and up to 1 amp for the second, with an optional second stepper or bi-directional dc driver daughtercard ...
