Stepper motors with integrated driver SMD-4.2mini V.2.1 - 1

SMD-4.2mini V.2.1 Stepper motors with integrated driver SMD-4.2mini V.2.1 Drivers SMD-4.2mini V2.1 were designed for work with ” stepper motors NEMA34 size with maximum current per phase 4.2 Amp (SM8680). Stepper motors SM8680 with integrated drivers are ready for work compact stepper drive. The driver has internal pulses generator, which makes it possible to control a stepper motor without using of any external signal sources. Newest circuit boards are used in the design of this renewed version of drivers V2.1. These circuits provides an excellent dynamics of stepper motors, fast acceleration and sufficient torque at the highest speeds. Control methods: • Pulse position control (STEP/DIR) • Analog speed control (by potentiometer) The main parameters: • Current per phase: 4.2 Amp • Power supply: 24 - 48 VDC • Microstepping mode - 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128 • Range of pulse frequency of internal generator 70 - 1200 Hz • Maximum holding torque: 45 kgf*cm • Motor rotor inertia: 1400 g*cm2 Dimensions of stepper motor SM8680 with built-in driver SMD-4.2mini V.2.1: Tallinn Science Park Tehnopol, Phone: + 372 6559914, Maealuse st. 4, Tallinn 12618, Estonia e-mail: sale@smd.ee
