Rexroth MSKO40C-NN-M1-UP1-NNNN

Rexroth MSK040C-NN-M1-UP1-NNNN Product Details

The Rexroth MSK040C-NN-M1-UP1-NNNN is a high-performance synchronous servo motor belonging to the IndraDyn S (MSK) series. These motors are known for their compact design, high torque density, and precise control capabilities when paired with IndraDrive intelligent drive systems. The "MSK" designation stands for servo motors, and "IndraDyn S" is another marketing name for the same series.

The specific designation "MSK040C-NN-M1-UP1-NNNN" provides the following information:

• MSK: Indicates it's a servo motor from the IndraDyn S series.

• 040: Specifies the motor's frame size (height and width). MSK040 motors have a width of 82 mm and a height of 124.5 mm.

• C: Denotes the motor's length. For the MSK040C, the length is 185.5 mm.

• NN: Indicates the cooling method is natural convection (self-cooling).

• M1: Signifies the presence of an optical encoder, multi-turn absolute Hiperface, with 128 signal periods. This provides high-resolution feedback for precise positioning.

• UP1: Indicates a 240-degree rotatable plug (U), a shaft with a keyway and a shaft seal ring (P), and a 4 Nm electrical release holding brake (1).

• NNNN: Represents the standard version of the motor, not explosion-proof.

Product Parameters

While specific parameters can vary slightly and are best confirmed with the official datasheet, typical parameters for an MSK040C motor include:

• Frame Size: 040

• Length: C (185.5 mm)

• Cooling: Natural convection (NN)

• Encoder: Optical, multi-turn absolute Hiperface, 128 signal periods (M1)

• Holding Brake Torque: 4 Nm (indicated by '1' in UP1)

• Maximum Speed: Typically up to 7,500 rpm (depending on the winding code, which is not fully specified in the "NNNN" part and would usually be a numerical value like 0450 or 0600 in a complete part number).

• Maximum Torque: Varies with the specific winding code. For example, an MSK040C-0600 can have a maximum torque of 8.1 Nm.

• Continuous Torque: Varies with the specific winding code. For example, an MSK040C-0600 can have a continuous torque of 3.1 Nm (at 100 K).

• Maximum Current: Varies with the specific winding code. For example, an MSK040C-0600 can have a maximum current of 12.4 A.

• Continuous Current: Varies with the specific winding code. For example, an MSK040C-0600 can have a continuous current of 4.7 A (at standstill).

• Winding Resistance & Inductance: Dependent on the winding code.

• Voltage Constant & Torque Constant: Dependent on the winding code. For example, an MSK040C-0600 can have a torque constant of 0.95 Nm/A and a voltage constant of 58.2 V/min-1 (at 20 °C).

• Rotor Inertia: Approximately 0.00014 kg*m² (for an MSK040C-0600).

• Weight: Around 3.6 - 3.9 kg (including the brake).

• Protection Rating: IP65 (dust-tight and protected against water jets from any direction).

• Insulation Class: 155 (according to DIN EN 60034-1).

• Ambient Temperature Range: Typically 0 to 40 °C.

Note: The "NNNN" at the end of the part number often represents specific winding characteristics and might need to be replaced with a numerical code for a complete and precise specification.
