High-torque servos integrate gears to
save space
The Allen-Bradley MPG-Series of integrated gear servomotors will be of particular interest to engineers designing machines requiring high torque servo solutions for rotary loads.
The Allen-Bradley MPG-Series of integrated gear servomotors will be of particular interest to engineers designing machines requiring high torque servo solutions for rotary loads Designed to work with the Rockwell Automation Kinetix and Ultra families of servo drives, the MPG-Series integrated gear servomotors are available in three frame sizes to provide continuous stall torque from 14 to 400Nm and peak torque from 32 to 1300Nm

Passport to safety
In today's marketplace, you have to think globally: that is where functional safety can help.
Low-cost gantries provide rapid motion
Rockwell Automation's Hercules low-cost gantries provide the rapid point-to-point motion common in the electronics/general assembly industries.
By combining the motor and gearbox into a single housing, size is reduced by 40% over conventional solutions and overall weight is some 25% lower.
A traditional motor and gearbox solution requires the gearbox input pinion to fit the motor output shaft and the motor mounting faces and hole centres to align with those of the gearbox.
The motor's torque and speed characteristics also need to be matched to those of the gearbox.

The modular design of the Kinetix servo drives helps minimise wiring time and related costs by greatly reducing the total number of connections.
Safety services boost productivity
Through effective hazard assessment, Rockwell Automation safety consultants can evaluate a manufacturer's equipment, identify guarding deficiencies and recommend machine guarding solutions.
In addition, there is the issue of who takes responsibility for the reliability and performance of the combined units, and the question of repeatability in the correct selection and assembly of the motors and gearboxes.
The integrated design of the MPG-Series overcomes all these selection and mounting problems.
In addition, the gearbox is carefully matched and optimised for use with the motor, ensuring a perfect, worry-free combination every time.
Units are lubricated and sealed for life, providing "fit and forget" reliability without the need for routine maintenance.
Another key feature of benefit to over-stretched commissioning engineers is the smart feedback technology that provides plug and play connection with automatic configuration, considerably reducing the time required to set up and configure the drives.
Also, of particular note for design engineers, the shaftless design allows loads to be directly bolted to the unit, providing a positive drive with a smaller moment of inertia, while the dynamic operating range allows shorter machine cycle times.
The standard ISO9409 mounting flange fits most standard machines and the complete unit is IP64 rated.
Backlash is limited to just 3arc-min and a 24V DC failsafe brake is fitted as standard.
The new MPG-Series of integrated gear servomotors is a significant addition to the growing Rockwell Automation range of servo actuation solutions.
Typical applications might include case packers, gantry robots, rotary tables, palletisers and AGVs, although any application where high torque is required in a small package will benefit. Request a free brochure from Rockwell Automation ...
