From Mitsubishi Electric: Low-profile direct drive motor provides direct control with accuracy of a servo motor

Mitsubishi Electric Automation, Inc. Vernon Hills, IL, says that its new low-profile direct drive motors (TMRG2M/ TM-RU2M) will interest machine designers and end users looking for direct control of a load without traditional transmission components. Built for speed and precision, it provides a smaller footprint and allows for more compact, efficient and precise machines than those typically built using rotary servo motors. Applications for the new motor include coating and vapor deposition systems, index tables, tool changers, rotary material handling robots, and rotary axis on XY inspection positioning systems.

Unlike rotary servo motors that are coupled to a load with a mechanical transmission such as a gear, coupling or belt, the TM-RG2M/ TMRU2M is coupled directly to a load, resulting in greater positioning accuracy, reduced energy use and less maintenance. Users can reduce installation space while combining direct control with the accuracy of a servo motor. It also allows for flexibility when sizing by allowing for compatibility with larger-capacity servo amplifiers such as Mitsubishi Electric’s MR-J4-40B (-RJ) with the TM-RG2M/TM-RU2M 004E30 to further increase torque.

There are two installation methods: flange-type with pilot; table-type with positioning pinholes.

The TM-RG2M/TM-RU2M motor reduces the complexity of traditional mechanical power transmission systems which increases the machine efficiency and reduces downtime/maintenance by eliminating mechanical components. It provides all the advantages of a servo motor in a compact package that is capable of supporting and driving a load directly.
