Product Description:

The DBL4N00750-0R2-000-S40 Synchronous Servo Motor provides consistent performance and longer service life in a variety of industrial motion control systems. Manufactured by Kollmorgen, this motor provides a continuous stall torque of 7.5 Nm to guarantee consistent torque output.

With a continuous stall current of 4.1 A and an operating current of 4.2 A, the DBL4N00750-0R2-000-S40 synchronous motor remains stable under full load with negligible thermal drift. This motor operates at a rated mains voltage of 400/480 VAC, which enables its compatibility with a wide range of standard industrial power systems. The rated speed range of this servo motor is between 3000 and 3600 RPM to enable flexibility for high-speed positioning and cyclic operations. For feedback, this motor supports both two-pole hollow-shaft resolvers and high-resolution encoders to provide precise positioning and speed sensing. The DBL4N00750-0R2-000-S40 has a shaft of 19 mm diameter and a 40 mm length to ensure convenient compatibility with numerous types of coupling and loading arrangements. This synchronous motor has an IP64 protection class for protection against dust entry and splashing water, and is appropriate for use in situations with moderate contamination.

This DBL4N00750-0R2-000-S40 motor is S1 duty cycle rated, which allows it to run continuously without overheating. This motor is also compliant with Vibration Class N according to DIN ISO 2373 to ensure stability in operations under typical industrial vibration levels. The use of neodymium magnets improves this motor's dynamic response and responsiveness to aid quick reaction to control commands. This motor's inertia of 4.3 kg·cm² provides dynamic response and system stability. This motor has a power rating of 2.02 kW, which makes it ideal for medium-to-high demand servo applications that need both speed and torque accuracy.

Frequently Asked Questions about DBL4N00750-0R2-000-S40:

Q: Why is a two-pole resolver used in the DBL4N00750-0R2-000-S40 servomotor?

A: A two-pole resolver provides absolute position feedback even at power-up. It ensures robust performance in environments with electrical noise.

Q: How does the vibration class N affect motor performance in DBL4N00750-0R2-000-S40?

A: Class N vibration ensures the motor runs smoothly with minimal mechanical stress. It helps reduce bearing wear and vibration-related failures over time.

Q: What is the importance of using neodymium magnets in this servomotor?

A: Neodymium magnets allow for stronger magnetic fields in a compact size. This results in faster dynamic response and higher torque density.

Q: How does the IP64 rating benefit the DBL4N00750-0R2-000-S40 motor in practical use?

A: IP64 protects the motor from dust ingress and splashing liquids. It enables safe operation in moderately harsh environments without additional enclosures.

Q: Why is the inertia of 4.3 kg·cm² important for DBL4N00750-0R2-000-S40?

A: This inertia level balances quick acceleration with motion stability. It’s ideal for applications involving frequent speed changes or load variations.
