The KST-57D33-0005 is a robust 1.8° two-phase stepper motor engineered to provide high torque and precision for a variety of motion control applications. With a rated current of 4.2A and a holding torque of 1.1N·m, this motor is ideal for systems such as CNC machinery, automation equipment, and robotics.

This stepper motor is designed with a phase resistance of 0.4Ω ± 15% and phase inductance of 1.4mH ± 20% at 1KHz, ensuring smooth and efficient operation. It also features an insulation resistance of 100MΩ min. at 500V DC, with Class B insulation, allowing it to operate reliably even in higher temperature environments. The 500V AC withstand voltage ensures that the motor can endure harsh operating conditions.

The KST-57D33-0005 has a rotor inertia of 280g·cm² and a weight of 600g, making it suitable for applications requiring a balance between power and precision. This motor offers excellent performance in dynamic systems where reliability and low mechanical inertia are essential.
