This beefy TB6600 4A Stepper Motor Driver is a powerful PWM chopper-type stepping motor driver, designed as a 2-phase single-chip bipolar sinusoidal micro-step driver, and suitable for driving both 2-phase and 4-phase stepper motors at up to 4A Peaks. It offers a nice wide control voltage range, from as low as 3.3V to as high as 24V, allowing it to be operated from a dedicated CNC Controller Board, or simply from a little microcontroller like an Arduino Board.

Built to offer high torque at high speeds, at the cost of low holding torque when not running, thes Stepper Drivers uses a current loop subdivision control, which ensures a very low motor torque ripple and very smooth operation at low speeds. Despite the low holding torque, when the motors are running, this drive maintains good positional accuracy due to the high-speed torque. As such, it is most often used within CNC milling machines, engravers and other workshop tools that require high torque at high speed – in which holding torque is not vital for quality results.

The TB6600 stepper motor driver also comes with an automatic anti-overheating mechanism called a semi-flow function, in which it reduces the current of the circuit by 50% when no signals have been received for 200ms. Additionally, it is recommended to leave about 20mm of space around the unit clear, so as to ensure efficient heat dispersion and to avoid heat-related problems.

The TB6600 has been tried and tested to work perfectly with the NEMA17, NEMA23, NEMA24 and NEMA34 stepper motors.
