Product Description

The Shengke STMT-O-6.5-45 is a compact, high-performance STMTO stepper motor featuring a 45mm frame size, optimized for precision motion control. Designed with a 2-phase configuration, it operates across a wide voltage range of 12-48V DC, supporting microstepping resolutions up to 25600 steps/revolution. The motor interfaces directly with common stepper drivers via pulse/direction signals, offering compatibility with RS-485, CAN, and Modbus protocols through external adapters. It operates efficiently in industrial environments within a temperature range of -20°C to +70°C. Ideal for automation, CNC machinery, and robotics, this 45mm frame stepper motor delivers exceptional torque (up to 6.5Ncm) while maintaining low noise and minimal vibration. Key advantages include robust construction and seamless integration with modular systems, though it requires precise current tuning to avoid overheating. The motor includes a built-in encoder for positional feedback with a resolution of 0.9 degrees, enhancing closed-loop accuracy. Compact dimensions (45x45x60mm) make it suitable for space-constrained installations.
