Application & Integration FAQs

What servo drive should I use with the SGMG-05A2AB?

Pair this 200V, 3.8A motor with a compatible Yaskawa Sigma series drive, such as the SGDH-50AE or SGDH-60AE. Ensure the drive's continuous output current rating meets or exceeds the motor's 3.8A for optimal performance.

How do I interpret the “A2AB” suffix in the model number?

For the Yaskawa SGMG-05A2AB, this typically indicates specific options: a standard keyed shaft, a specific flange type, and the presence of a standard incremental encoder without an integral brake. Always confirm exact options with the manufacturer's datasheet.

Can I use this IP65 motor in a washdown environment?

The IP65 rating protects against low-pressure water jets from any direction. It is suitable for areas with occasional splashing or cleaning. For sustained high-pressure washdown, a higher protection rating like IP67 or IP69K would be recommended.

What is the practical difference between rated torque and maximum torque?

Rated torque (1.59 Nm) is the continuous torque the motor can deliver without overheating. The maximum (or peak) torque is higher (typically 3-5x rated) and is available only for short bursts (seconds) during acceleration or deceleration, before thermal limits are reached.

What's a key mechanical consideration during installation?

Ensure perfect alignment between the motor shaft and the driven load. Even minor angular or parallel misalignment can cause premature bearing failure, vibration, and reduced performance. Always use a proper coupling designed to accommodate any residual misalignment.
