How Resolvers Work

resolver photosResolvers are absolute angle sensors that use entirely passive transformer technology. Resolver offer reliability benefits over other technologies and are perfectly suited in extreme temperature, oily, dusty or even radio active environment. Resovers are now supported in all new and updated version of Roboteq's brushless motor controllers. Resolvers is an analog position sensor that is absolute ov...

How SSI Encoders Work

ssiWhen operating brushless DC motors, knowing in real-time, and with precision, the position of the rotor is a prequisite to best performance in sinusoidal commutation. While numerous sensor techniques exist and are supported by Roboteq, Synchronous Serial Interface (SSI) is by far the best at is provides an absolute position with great resolution at very fast update rates. Synchronous Serial Interf...

Building a Magnetic Track Guided AGV

automated-guided-vehicle built with magnetic guide sensorAn automated guided vehicle (AGV) can be built with as little as two Roboteq components: An MGS1600 magnetic guide sensor, and one of the many dual channel motor controllers available in Roboteq’s catalog. This application note will use a Roboteq MDC2230 dual channel controller, however the techniques described are identical for all other controller models.

MicroBasic eases Fast Prototyping of Innovative Electric Push Scooter

kickscooter-allA Push Scooter is definitely a high volume consumer item requiring a dedicated motor controller and battery system. Before redesigning the controller and supporting electronics to fit it nicely into the scooter's base, an off the shelf Roboteq MBL1660 single channel motor controller was used to test and validate some innovative ideas. Unlike all other electrical push scooters, this one does not ha...

Driving Mecanum Wheels Omnidirectional Robots

See how to build an omnidirectional robot with just two Roboteq dual channel DC motor controllers to independently drive four mecanum wheels. The two controllers operate as a single four channel drive over a CAN network.

Field Oriented Control (FOC) Made Ultra Simple

foc iconEvery modern motor controller for Brushless motors now features Field Oriented Control (aka VectorDrive). But what is it exactly and how does it work? One way to figure this out is to look on Wikipedia, or most other articles on the subject on the internet. There, the explanation are complete and accurate but often filled with too much math formula to actually make practical sense of it. Yet, Fiel...
