Motor Features Used By Motion Controller Technologies
Use of frameless and brushless motors
These are electric motion control motors that have gained popularity over the years owing to their numerous advantages. The frameless motors contain a stator and rotor assembly that has permanent magnets. As the name implies, they do not have shafts, bearings and end bells. They are designed to enhance the rigidity of integrated devices. They are preferred for industrial applications because they facilitate achievement of compact and weightless footprint by OEMs and offer excellent torque density. On the other hand, the brushless motors have commutator contacts in place of brushes that provide current to motor windings. Brushless motors offer high speed, higher power to weight ratio and low maintenance that makes them more effective for use as compared to brushed motors.
Compact size motor drives
As the world moves towards miniaturization, the demand for compact sized linear motion actuators and motion control devices increases. This in turn increases the demand for compact sized motor drives that are designed with onboard memory and processing power that allow them to perform more industrial functions as opposed to just moving current to motors. Compact sized motor drives are gaining momentum because they also help machine operators to detect defects during operation and clear underlying congestion without altering the lockout tag.
Programmable logic controllers are mainly used in motion controllers with electric linear actuators. These PLCs provide enhanced control over speed, torque and acceleration. But, as technology advances, the programmable logic controllers are designed to handle different motion control tasks quite effectively and efficiently. Above all, they facilitate better connectivity as compared to their counterparts.
Motion controllers in different industry settings demand different motor performances. The role of motors remains focused on offering greater efficiency, reliability and precision. The motors are the backbone of most applications in a myriad of industry settings.
