Product Description:

Kollmorgen created a E42HCHT-LNK-NS-01 hybrid stepper motor that is suitable for the applications requiring constant motion control and torque delivery are ideal for this motor. The mounting technique is based on the robust NEMA pattern, which ensures mechanical stability even when subjected to loads.

The E42HCHT-LNK-NS-01 hybrid stepper motor is a NEMA 42 compliant model with a 4.28-inch diameter. Two stacks make up the rotor stack, which allows for optimal torque output. A laminated rotor guarantees efficient magnetic response during construction. A straight key ensures perfect torque transfer in the single-shaft mode. Motors with windings that produce maximum torque at low speeds are ideal for use in industrial automation when low speeds are required. The winding/lead type has an improved ability to handle current due to its 4-lead parallel connection. In order to facilitate structured wiring, the E42HCHT-LNK-NS-01 comes with a terminal board that is accessible via a conduit connector and is splashproof. The motor is specifically designed for reliable operation and heavy-duty mounting, falling under the NEMA 42 frame category. It has a shaft seal built into its unique sequence design and functions without feedback from encoders. The measured phase resistance is 0.41 ohms with a tolerance of plus or minus 10%.

Holding torque of E42HCHT-LNK-NS-01 motor is 18.02 Nm, or 2552 oz-in. The motor can withstand a phase current variation of up to 10% when running at 7.9 A DC. The winding's inductance of 7.8 mH allows for steady current flow and the growth of magnetic fields. The sealed connection is made possible by the motor's design, which permits integration through a conduit entrance. Stable torque output is supported by the 4-lead parallel winding, which helps to reduce inductive losses. Under rated conditions, the product guarantees steady torque delivery and accurate motion control.
