SGMJV-04ADA61

What type of component is this?

This unit is a rotary servo motor designed for precise motion control in automated machinery. It belongs to the Sigma-V medium-inertia range and is intended for applications that need accurate positioning, stable speed control and responsive torque performance.

What are the main electrical ratings?

The motor is rated at 400 W with a 200 V AC supply class. Its rated current is 2.7 Arms, with an instantaneous maximum current of 9.3 Arms.

What speed and torque performance can be expected?

This model has a rated speed of 3000 rpm and a maximum speed of 6000 rpm. Rated torque is 1.27 Nm, and instantaneous peak torque is 4.46 Nm, making it suitable for dynamic motion tasks where short bursts of higher torque are required.

What encoder specification does it use?

The SGMJV-04ADA61 is fitted with a 20-bit incremental serial encoder as standard. This gives high-resolution feedback for precise positioning and repeatable motion control.

Does this version include a holding brake?

No. This version is supplied without a holding brake. In the model coding, the final digit indicates a version without optional brake or oil seal features.

What shaft style does this motor have?

This version has a straight shaft with key and tap. That configuration is often chosen where secure mechanical coupling is needed and where keyed transmission components are already specified in the machine design.

What is the mounting size?

The motor uses a 60 mm x 60 mm flange face. For machine builders and maintenance teams, this is an important dimension when checking mechanical fit within existing assemblies.

What enclosure protection does it offer?

The motor is rated IP65, except at the shaft opening. This helps protect the main body against dust ingress and water jets in appropriate industrial environments, although the shaft area should still be considered in the overall installation design.

What types of applications is it commonly used in?

Typical uses include semiconductor equipment, chip mounters, PCB drilling stations, robots, material handling systems and food processing machinery. It is a good fit where compact size, fast response and accurate control are important.

What cable options are typically used with this motor?

For 200 W and 400 W versions in this range, matching power cables are available in standard and flexible types, commonly in lengths from 3 m to 20 m, with longer cable configurations available for some installations. Encoder cable selection depends on whether the application uses incremental or absolute feedback arrangements.

Are there any installation points to keep in mind?

Yes. Power and encoder cables should be routed separately from I/O signal wiring, with at least 30 cm spacing recommended. Where cable runs become longer, voltage drop and encoder extension requirements should be reviewed as part of the installation layout.

Is this motor suitable for high-inertia loads?

It is designed as a medium-inertia servo motor, but the load inertia still needs to be checked against the application. For the 400 W frame size, the allowable load moment of inertia is given as up to 10 times the rotor moment of inertia as a general guideline.
