Stepper Motor Drivers

Tiny Controls present Stepper Motor Drivers that offer precise as well as compact industrial quality at reasonable costs.

Our Stepper Motor Drivers are based on sinusoidal current chopping so no resistance is required to be placed in series with motor when the motor is driven at a higher voltage than for the motor rated. The advantage of driving the motor with higher voltage results in a motor capable of achieving higher speed.

Bipolar Microstep Drivers for Stepping Motors

When the basic step of a motor are subdivided it results in microstepping. Microstepping is achieved by controlling the current of two motor windings resulting in the production of a number of intermediate step positions (Microsteps) between full-step positions (Full Steps). It is essential to note the intermediate positions must be equally divided (as much as possible) while the motor is running so as to produce smooth motion and approximately equal torque on all microsteps.

Precise and Compact Industrial Quality at Reasonable Cost

Accurate microstepping places a great deal of accuracy demand on current control profile at all levels of currents on the drive. The phase current profiles required in microstepping a stepper to produce the microsteps are sinusoidal. Browse the Help Zone for fundamentals of stepper motor theory. We are constantly adding tutorials and circuits to this section.

Our drivers are optimized for high performance while reducing the current consumption and heat generation.
