REXRTOH MSK070D-0450-NN-M1-UP1-NSNN High-Torque Servo Motor

The REXRTOH MSK070D-0450-NN-M1-UP1-NSNN represents a powerful member of the MSK series of synchronous servo motors, engineered to deliver superior torque output for demanding industrial automation tasks. With its larger 070D frame size, this motor is designed to handle applications requiring significant mechanical power while maintaining the precision and dynamic response characteristic of the MSK family. The comprehensive model code precisely defines its performance envelope, mechanical configuration, and standard features, making it an ideal choice for system integrators designing high-performance motion axes.

Model Code Analysis and Key Features

The detailed model number provides a complete technical specification:

• MSK070D: Identifies the motor series (MSK) and the specific frame size (070D). The "070D" indicates a larger physical frame than the 060C variant, typically corresponding to higher continuous and peak torque ratings.

• 0450: Specifies the motor's rated speed or a key performance parameter. In this context, "0450" often corresponds to a rated speed (e.g., 4500 rpm) and defines the motor's base speed for nominal operation.

• NN: Denotes standard options for brake and feedback. The first 'N' typically indicates no integrated holding brake. The second 'N' specifies a standard, high-resolution feedback system, such as a single-turn or multi-turn absolute encoder.

• M1: Defines the mechanical flange interface, including its type, dimensions, and mounting pattern, ensuring compatibility with standard couplings and mechanical assemblies.

• UP1: Specifies the shaft design and sealing. This includes the shaft geometry (e.g., with keyway per standard), shaft sealing to prevent ingress, and the resulting ingress protection (IP) rating.

• NSNN: A set of variant codes specifying additional standard features, which may include standard winding, standard connector type, and standard surface finish/paint.
