HSM307 by Kollmorgen

The Kollmorgen HSM307 servo motor, part of the HSM Brushless Servo Motors series, delivers precise motion control in industrial automation environments, operating at a maximum operating speed of 5000 rpm. This compact servo motor is engineered for high dynamic response, leveraging a rotor moment of inertia of 0.00003 kg·m² to achieve rapid acceleration and deceleration profiles. With an optimized sine wave torque constant of 0.28 Nm/A and a square wave torque constant of 0.31 Nm/A, the HSM307 provides consistent torque delivery across its operating range. Its robust construction and advanced electromagnetic design ensure reliable performance under continuous duty cycles. The integration of a voltage constant of 34 V/krpm further enhances compatibility with diverse drive systems, making the HSM307 a versatile solution for precision positioning.

The HSM307’s technical specifications include a winding resistance of 0.66 Ohms and a phase-to-phase inductance that supports stable current control. Vibration-induced torque ripple is minimized by a damping coefficient of 0.01 Nm/krpm (0.09 lb-in/krpm), while mechanical stability is ensured by a friction torque of 0.014 Nm (0.12 lb-in). The motor’s net mass of 2.6 kg (5.8 lb) provides an excellent power-to-weight ratio, facilitating agile system designs. The device features six poles for smooth electromagnetic interaction and low cogging torque. Classified as a product type: Servo Motor, the HSM307 adheres to stringent manufacturing tolerances, with phase-to-phase resistance maintained within ±10% at 25°C.

In operational use, the HSM307 exhibits efficient thermal management, with a thermal resistance of 1.2 °C/W that enables prolonged continuous operation without performance degradation. The low rotor moment of inertia combined with precise torque constants ensures rapid settling times and high repeatability in positioning tasks. Mechanical vibration and noise are suppressed through optimized damping, supporting applications requiring quiet operation. The servo motor’s design accommodates diverse mounting configurations and offers consistent output even under variable load conditions, ensuring stable closed-loop control.

The HSM307 integrates seamlessly with Kollmorgen’s advanced servo drives and motion controllers, supporting daisy-chain communication and real-time tuning. Its compatibility with standard industrial feedback protocols simplifies system commissioning and diagnostics. Ideal applications include pick-and-place robotics, CNC tooling, semiconductor handling, and automated assembly lines, where high-speed performance and precise torque regulation are crucial. By combining the proven reliability of Kollmorgen engineering with the flexibility of the HSM Brushless Servo Motors series, the HSM307 meets the rigorous demands of modern industrial automation.
