BLDC motors are famous for their durability, efficiency, and controllability. But while durability and efficiency are inherent to brushless DC motors themselves, the ability to control them depends on the feedback mechanism used. Which is why TRINAMIC Motion Control GmbH & Co. KG introduces their latest ABN encoder optimized for BLDC motors: the TMCS-28-x-1024.
“Incremental encoders are key enablers when working with BLDC motors,” according to Michael Randt. “They not only increase the application’s performance they also relieve engineers from the increasing pressure of miniaturization and efficiency by allowing for smaller drives.”
Enabling to drive the motor with the exact torque and rpm required for an application, optical incremental encoders for brushless DC motors as well as stepper motors make it possible to use smaller drives in applications, opening up new markets to them. What’s more, encoders like the TMCS-28-x-1024 ABN encoder also allow for predictive maintenance when used correctly.
More and more indicators show that in the near future, applications will be able to predict when parts need to be calibrated, checked for wear and tear, or even need replacing. Keeping track of runtime is one way of doing so but tracking the exact number of handlings – and type of handling – using encoders is more accurate.
Using encoders for BLDC motors, or other means of feedback systems such as closed-loop ICs for stepper motors, predictive maintenance can be built into any application. This way, incremental encoders not only increase the efficiency by driving motors the best way possible, it further increases efficiency by reducing downtime to a minimum.
Besides offering single encoders, Trinamic now also offers both stepper motors mounted with encoders and BLDC motors with encoders mounted to them.
