Product Description:

The PMB31D-20116-01 acts as a powerful servomotor, which has been engineered for tough industrial automation duties. It is ideal for industrial operations that cannot compromise with accuracy. This motor is built as a part of the PMB Brushless servo range. It is engineered to provide a stall torque (steady) of 4.9 Nm. This steady torque helps keep motion constant. Furthermore, it helps keep the motion consistent over long periods of time. Its maximum working speed is an astounding 5750 RPM. The motor weighs 5.2 kg (kilograms), which makes it both strong and easy to work with, so it may be used in a variety of ways. The PMB31D-20116-01 has an inbuilt digital encoder that gives accurate feedback for closed-loop control.

This feature makes sure that the motor is positioned correctly and that the speed is controlled, which makes it perfect for tasks that need high repeatability and precise motion control, such robotics. The digital encoder input and control make the system more responsive and increase its overall performance, which leads to more production and less downtime. The PMB31D-20116-01 works well with Pacific Scientific's sophisticated servo drive systems, such as the SC/SCE900, PC800, and PC3400 series. These drives are fast, smart, and easy to use all at the same time.

For example, the PC3400 servo series offers a small, affordable solution with smart technology, programmable I/O, and support for numerous control modes. This lets engineers customize the drive/motor combination to meet the demands of their individual application. They are made with Class H insulation and come with extras like overtemperature thermistors and brakes. They are also known for being safe and meeting international standards.
