Product Specifications

Technical details and manufacturing context for Stepper Motor Driver

Definition
A stepper motor driver is an electronic power amplifier that receives low-level control signals from a microcontroller or indexer and converts them into high-power electrical pulses to drive a stepper motor. It provides the necessary current and voltage to energize the motor windings in a specific sequence, enabling precise control of position, speed, and torque without requiring feedback sensors for basic operation. The driver is designed for use with two-phase bipolar stepper motors, commonly NEMA 17, 23, and 24. It operates from a DC supply voltage of 24–48 VDC and can deliver an output current of 1.0–4.2 A per phase. The driver supports microstep resolutions from 2 to 256 steps per full step, allowing for smooth motion and reduced resonance. It accepts step pulse frequencies up to 200 kHz and features optocoupler-isolated inputs for pulse/direction or CW/CCW control signals, compatible with PLC and MCU outputs at logic voltages of 5–24 VDC. The device is a single-axis driver, controlling one stepper motor. It is housed in a compact panel-mount enclosure with dimensions of 118×75×33 mm and weighs 0.3 kg. The operating temperature range is 0–50 °C, with storage from -20 to 70 °C. The protection rating is IP20 per IEC 60529, indicating indoor use and protection against solid objects greater than 12.5 mm, but not against water. The driver is constructed with a printed circuit board, semiconductor components (MOSFETs or IGBTs), an aluminum heat sink, and a plastic housing. All specifications are reference values and must be verified with the legal manufacturer for the specific model and application.
Working Principle
The driver receives digital pulse and direction signals from a controller. Each pulse corresponds to one step of the motor. The driver's internal circuitry, typically using MOSFETs or IGBTs, amplifies these signals to switch current through the motor's phases in a predetermined sequence (full-step, half-step, or microstep). This creates a rotating magnetic field that causes the motor's rotor to move in discrete angular increments. Advanced drivers incorporate current control, decay modes, and microstepping to smooth motion and reduce resonance.
