Selection and Application of KOLLMORGEN E/H Series Stepper Motor

Refer to the general specifications: Understand the basic electrical parameters, insulation level, protection capability, etc. of the motor to ensure compliance with the application environment.

Analyze performance data: Conduct in-depth research on detailed performance tables for different stack lengths (1 stack, 2 stacks, 3 stacks, 4 stacks) and winding configurations (parallel, series, single pole). These tables provide key data including holding torque, rated phase current, phase resistance, phase inductance, thermal resistance, rotor inertia, weight, and shaft load (radial and axial forces). For example, the torque range of the E3/H3 1-stack motor ranges from approximately 1.58 Nm to 1.71 Nm, while the 4-stack enhanced (E34 series) motor can provide a holding torque of up to 9.18 Nm.

Reference mechanical drawings: The document provides detailed dimensional drawings for the E3/H3 and E4/H4 series, including standard front-end covers, heavy-duty front-end covers, splash proof structures, and various external dimensions with MS connectors and encoder options. The user needs to confirm whether the installation hole position, shaft extension size (standard keyway, flat or rear shaft extension, etc.), and total length comply with the mechanical design.

Build part number: Based on all determined technical parameters and options, construct a complete motor model according to naming conventions.

Electrical connection and encoder integration: achieving precise control

To achieve correct docking with the driver, the document elaborates on the wiring methods for different winding configurations:

4-wire bipolar connection (parallel and series): Corresponding lead colors, terminal numbers, and MS connector pin definitions are provided to guide users in achieving the most efficient current drive mode.

6-wire single pole connection: clarifies the connection method of the center tap, suitable for single pole drivers.

For applications that require closed-loop feedback or higher positioning accuracy, the E/H series offers optional incremental optical encoders. There are mainly two types of encoder options: PD type (500 wires/rpm) and PF type (1000 wires/rpm). They all use differential line drive outputs, providing dual channel orthogonal signals and index (Z) signals, with a maximum response frequency of 100 kHz and a wide operating temperature range of -40 ° C to 100 ° C. The encoder is integrated through a 10 pin connector (matched with MS3116F12-10S plug), with clear wiring definitions for system integration. The installation of encoders provides the possibility to improve system accuracy, achieve out of step detection, and more complex motion control algorithms.
