Kollmorgen SILVERLINE H series brushless servo motor and matching amplifier

Overall Overview of the Product

The Kollmorgen SILVERLINE series focuses on low-cost and high-precision motion control, providing a complete solution of "brushless servo motor+dedicated amplifier". The mechanical size of the motor is compatible with NEMA 23 and 34 stepper motors, and can be directly replaced to improve performance while maintaining reliability; The amplifier is divided into basic driver type (SO/RO/OL) and integrated locator type (BJR/BJRL), covering different control requirements. The product reduces the difficulty of selection and deployment through clear adaptation relationships, detailed wiring definitions, and installation parameters, and is suitable for cost sensitive scenarios such as automation equipment and precision positioning systems.

Core Model and Performance Parameters

The motor is divided into H-23X (2.3-inch square frame) and H-34X (3.44-inch square frame), each series containing different stack length models. The core performance is shown in the table below:

H-232-G 0.415/58.8 0.93/131 162 4150 0.17 0.91

H-234-H 0.833/118 1.82/258 351 6000 0.23 1.27

H-342-H 1.26/179 2.65/375 470 6000 0.48 1.78

H-344-H 2.10/297 5.26/745 701 4050 0.92 2.65

H-348-H 5.26/745 14.21/2012 821 1850 2.66 6.32

Key Characteristics

Feedback system: Standard Hall sensor (120 ° commutation), requires external 5-24VDC power supply, optional 1000 wire incremental encoder (options such as 0200/0600/0802), supports speed/position closed-loop control;

Structural design: IP40 protection level, optional shaft diameter of 0.25 inches (only H-23X) or 0.375/0.5 inches, motor lead made of Teflon material (# 16 AWG), sensor lead made of # 26 AWG, length ≥ 18 inches;

Thermal performance: The working environment temperature is 40 ℃, the thermal time constant is 8.1-33 minutes, the thermal resistance is 0.9-2.9 ℃/W, and a heat dissipation plate (such as H-23X with 6 × 6 × 0.25 inch aluminum plate) needs to be installed as required.

Axle load limit

The motor shaft load needs to be matched with the speed, and the core limits are as follows:

H-23X series: 0.375 inch shaft pure radial load up to 30lbs (reduced to 5lbs at 6000RPM), 0.25-inch shaft load needs to decay according to the curve;

H-34X series: 0.375 inch shaft pure radial load up to 60lbs (reduced to 10lbs at 6000RPM), 0.5-inch shaft pure radial load up to 80lbs (reduced to 20lbs at 6000RPM);

Load application requirements: Radial load should be applied to the shaft end 0.75-1.0 inches to avoid overloading affecting the bearing life (design life of 20000 hours L10).
