Installing the 1000 Watt DMM servo spindle motor in place of the 750 Watt motor I originally tried. The new DMMTech part number is 86HDHTA6MK1. This motor is not listed on their website but is readily available and is the same physical size as the 86MDHTA6MK1 750 Watt motor. this makes for an easy swap. in this video I explain the reason for moving from the 750 Watt motor to the 1 kW motor and discuss the process used for calculating the inertia of the milling machine spindle.
