Application note and video for CNC machines

An application note convering conversion of a manual milling machine to a PC computer controlled CNC machine has been published.The machine used for conversion is an Optimum BF20L milling machine. The SimplexMotion100A motor units are used for the X/Y/Z axis drives and the SimplexMotionHub central unit is used for powersupply and motor connections to the PC computer.Spindle on/off and speed control is also implemented.
The SimplexMotion100A motors are suitable to replace step motors in this type of applications to get more performance and functionality to a marginally higer price.

A video is also available that shows the machine modifications and the workflow to do computer controlled 3D milling operations.

Swedish patent granted for novel motor sensor

The sensor technology used on the SimplexMotion line of integrated motor units has been subject for a patent application in early 2011. The application was submitted to the swedish patent office and has now been granted in November 2012. A PCT application has been filed with the original priority date from the swedish submission.

The patent covers rotor position sensing using the magnetic field from the motor magnets on outer rotor brushless motors and with the magnetic sensors on a tangentially arranged PCB circuitboard.

Further patent applications covering technologies in the field of mechatronics is under consideration.
