Software puts control system data on the record
Helps manufacturers automatically identify, gather and configure high-speed detailed data from any control system or human-machine interface software.
They pack 72% more torque into a motor which typically has a 19% smaller frame size and is 39% shorter than previous generations.
MP series motors are particularly suitable for applications such as automated production lines, high-speed packaging machines and material converting/rewind, where the compact dimensions of the new motor can be used to reduce the overall width of a multiple axis machine.
The motors feature a number of important technological advances.

High- Energy Neodymium Rare Earth magnets are used to provide an extremely powerful, lightweight rotor with low inertia.
Segmented 'tooth shaped' laminations are used to create individual segment stacks, which are wound before being assembled into the stator.
This unique construction opens the slot area, increases copper density and produces a smaller motor because of the shorter end turns this type of construction allows.
The torque-to-inertia ratio of the MP Series motors provides impressive acceleration characteristics.
For example, replacing a conventional motor with an MP Series could increase the speed in a typical application from 1000 to 1800 units/hour.
This is a significant benefit for machinery manufacturers where throughput and capacity can be a deciding factor.
For applications that require high-end accuracy and precision, the MP motors offer multiple feedback options, including intelligent, high resolution, absolute feedback devices, resolver and incremental encoders.
Connection to the motors is by means of pre-made cable assemblies to speed installation and reduce wiring errors.
Alternatively, customers can make up their own cables using industry standard ITT Cannon style connectors.
MP Series motors cost no more than the conventional motors they replace.
They provide a degree of protection to IP 66 and are based on IEC 110, 115 and 130 frame sizes to give a torque from 1.5Nm to 10Nm continuous (3.1Nm to 23.2Nm peak).
CE and UL approved, they are suitable for a wide variety of automated production applications in global markets.
The introduction of the MP Series represents a milestone for Allen- Bradley in the development of servo motors.
Their compact dimensions and exceptional performance provides a design platform for an entire new range of next generation motors. Request a free brochure from Rockwell Automation Anorad ...
