Product Description:

The E33NCHT-LDN-ND-01 is an excellent stepper motor with a wide range of applications in industries requiring precision movement and torque application at different speeds. This unit is a versatile addition to the category of the E series of Kollmorgen stepper motors. This unit uses an enhanced technology from SIGMAX that increases its output and efficiency more than the standard feature. This stepper motor focuses on cost-effectiveness, increased life span, and durability with integrated features, including laminated rotor types and UL-compliant NEMA 34 frame size. Its simple design, including the integrated shaft flats, also contributes to its wide range of uses and applications.

The E33NCHT-LDN-ND-01 is a reliable stepper motor with an ingress protection rating of IP65. This degree of protection ensures that the unit is completely protected against dust and can withstand water projection, making it excellent for various outdoor uses. It features a standard motor with a shaft seal to maintain and reduce noise and ensure protection. The three rotor stacks of the stepper motor increase torque and reduce vibrations while dissipating heat generated more effectively. The E33NCHT-LDN-ND-01 has a winding type that offers maximum torque at low speed for the appropriate application. This is a bipolar stepper motor that features 4 lead parallel connections using two coils and supplying current to both coils simultaneously.

The E33NCHT-LDN-ND-01 features a smooth modification type for its shaft and double shaft configuration setting. It has a lead wire connection style for improved hold on coupled machines and proper stability when performing precision tasks. The precise movement of 1.8-degree increments makes the 2-phase stepper motor idea suitable for various applications. The 200 full steps per revolution feature a step accuracy of -/+ 1.5 per cent. The insulation voltage rating of 340 voltage of direct current makes its safe for use in standard conditions.
