Product Description:
The E21NCHT-LDN-SS-03 serves as a precision motion control application stepper motor through its E Hybrid Stepper Motor technology. The motor was produced by Kollmorgen which provides both high performance and reliable operation for industrial automation. The motor can operate in industrial automation robotics and CNC systems. The motor works persistently in tough operational settings.
This E21NCHT-LDN-SS-03 stepper motor incorporates a round mounting design with 2.186 ± 0.002 inches [55.52 ± 0.051 mm] diameter. The motor reaches its maximum length of 10.56 inches when measured from the L1 point. The system requires MS connectors and optional encoder functionality to implement the design. The motor includes a basic shaft pattern with a 0.7500-inch (19.05 mm) diameter. The terminal board connections of this splash-proof construction can be selected with L or M options. Different designs of construction result in minor changes to thermal resistance measurements. The E21NCHT-LDN-SS-03 stepper motor can handle radial forces of 801 N for axial forces it maintains up to 156 N. The rotor inertia reaches 0.0083 units of kg-m² × 10?³. Enhanced series motors generate 2.43 Nm (369 oz-in) of torques for holding purposes. At the rated current phase levels reach 8.4 Amps each. Each phase of the component comes with standard 1.0 mH inductance. The lead wire construction employs a minimum #18-22 AWG cable based on motor lead types.
The E21NCHT-LDN-SS-03 stepper motor operates perfectly for systems that need exact motion control performance. The motor front shaft options consist of D-Flat and woodruff keys which depend on the equipment requirements. When configured in parallel mode the components have an equivalent resistance value of 0.13 Ohms. The device possesses a powerful structure together with state-of-the-art functions that result in reliable operation. The motor works well in CNC machines as well as automated manufacturing and robotics applications.
