Nema17 stepper housing with power connector and hall ref point.

This nema17 stepper motor housing is designed for Fischertechnik blocks. It also includes connectors for the motor wires and an additional 3pin connector for a hall reference point detection. This makes the connection of this Nema17 motor easier. The extra hall detector can be used to set a zero point of the motor. This can be very useful after a powerup. The hall detector is built into the housing and the necessary signal is given by a Neodymagnet D2x3mm which is located in the shaft adaptor. T
