KST-86D33-0001 1.8° Stepper Motor, 6.3A Rated Current, 2.9N·m Holding Torque, 86mm Frame Size

The KST-86D33-0001 stepper motor is an industrial-grade motor with an 86mm frame size, offering a 1.8° step angle and 2.9N·m holding torque. Designed to meet high-performance demands in applications such as CNC machines, robotics, and automation systems, this motor delivers precise and reliable motion control.

With a 6.3A rated current, it provides robust torque for heavy-duty tasks. The motor's phase resistance of 0.24Ω ± 15% at 25°C and phase inductance of 1.4mH ± 20% (measured at 1KHz, 1Vrms) ensure high efficiency, minimal energy loss, and smooth operation even at high loads. The rotor inertia is 1100g·cm², which contributes to the motor's ability to handle high torque without losing control.

Featuring Class B insulation with an insulation resistance of 100MΩ minimum (at 500V DC) and a withstand voltage of 500V AC for 1 minute, this motor is built for safety and durability in demanding environments. Weighing 1600g, it is optimized for use in applications where reliability and precision are crucial.
