Product Description:

The E33HRHA-LDS-SS-02 Stepper motor from Kollmorgen has been designed for high-torque and high-efficiency precision motion control applications. Maintaining dependable functioning in demanding automation systems is made possible by the motor's construction and its rated current of 8.6 A DC. The motor's consistent performance, made possible by its low inductance of 2.3 mH, improves the precision of the controls.

Operating efficiently is ensured by the E33HRHA-LDS-SS-02 motor's minimum power loss, thanks to its phase resistance of 0.23 ohms. The rotor's 9.1 oz-in² inertia allows for precise motion control and improved dynamic response. To ensure electrical stability that meets industrial safety standards, the insulation resistance is tested at 100 megohms at 500 V DC at 25°C. Operating at 40°C ambient temperature allowed for excellent heat dissipation that supported continuous performance in the motor's thermal resistance design. Applications requiring exact positioning and controlled acceleration are well-suited to the hybrid motor's improved torque characteristics, made possible by its design. The motor is designed to provide reliable performance that is essential for efficient automated motion control systems. Its design prioritizes torque stability that guarantees reliable performance. Automatic positioning with repeatable accuracy is supported by the controlled motion provided by the stepper motor.

When it comes to automated systems, the E33HRHA-LDS-SS-02 stepper motor is built to last. Its insulating resistance stops current leakage and guarantees safe electrical performance. The motor meets the needs of industrial automation thanks to its hybrid design that maximizes torque output. With a holding torque of 940 oz-in (6.64 Nm), the stepper motor gives the system excellent positioning capabilities and makes it more stable. The motor's extensive engineering satisfies the high standards of industrial-grade motion control. This motor is ideal for high-tech motion systems that require precision and long-term reliability.
