Product Description:

Kollmorgen developed the E21NCHT-LDN-PK-00 Hybrid Step Motor specifically for superior industrial automation. The motor comprises splashproof components that utilize terminal board wiring terminals. This ensures safe wiring connections to the motor.

The E21NCHT-LDN-PK-00 hybrid step motor demonstrates resistance against radial forces. It reaches 35 lb (156 N) which prevents damage to the system. This motor provides 180 lb (801 N) point load resistance along its axial direction to manage weighty duties. The motor adapts to versatile industrial installations because it requires 5 VDC supply voltage within ±10% tolerance range. The electrical operation benefits from a phase inductance of 2.7 mH. Position feedback with an optical incremental encoder is present on the E21NCHT-LDN-PK-00 hybrid step motor. The encoder provides two different line count selections at either 500 or 1000 lines. It belongs to a single-revolution cycle for diverse precision levels. The dual-channel quadrature output with index (Z) serves as the proper format for signal processing. The encoder implements differential line drive output technology. The motor weighs 3.2 pounds (1.45 kilograms) which ensures reliable operation during challenging usage situations. Being designed for exact motion control the motor includes rotor inertia of 0.0586 kg-m² x 10⁻³.

The E21NCHT-LDN-PK-00 hybrid step motor produces stable interference-free data transmission. Built with an output frequency of 100 kHz enables the encoder to deliver fast data processing. The motor system operates effectively within temperatures spanning from -40°C to 100°C of extreme environments. Long-term storage happens at the same temperature range which ensures equipment reliability. During installation, the motor exhibits a thermal resistance of 3.9 °C/W. This ensures proper heat elimination to the motor. The Kollmorgen Hybrid Step Motor receives thorough engineering for applications that need both precision and durable construction.
