NetGain is now offering a series of high performance motors in the 5kW to 35kW range (10 kW continuous).  This size motor may be ideal for the power train of light to mid-weight off road vehicles.  A 880 test motor with different shafts was obtained from NetGain and an overview of the mechanical aspects of the motor are outlined below.   

The NetGain Micro 880 system includes a 3-phase brushless motor that can operate from a DC power supply between 24 V and 180 volts.  The suggested inverter pairing depends upon the application, but the following are suggested by NetGain.  

X48600 for High Torque and Low Speed

X125 for Low Torque and High Speed

X1 for Maximum Torque and High Speed

X144 for High Torque and Maximum Speed (This is the same controller (inverter) employed in this 1992 BMW 325i blog.)

DSC02424 Comparison of the NetGain Micro 880 (40 pounds and on the left) and the NetGain Hyper9 that is used in this BMW 325i blog (130 pounds and on the right).  The Hyper9 is shown supported using the bottom half of the available motor mount.  Both motors can use the same NetGain SME AC-X1 Inverter.

DSC02406  Motor and shaft (shown) Part number IMP193-M881, for the motor and 1.125" shaft diameter, 1.50" length forged shaft (shown) with 0.25" keyway.  The right  side installs into the motor face.

(right) Part number IMP193-M883, for the motor and 13T spline (shown)

DSC02418 Close up of the drive side of the Micro 880.  Note the alignment pin at 3:00.  This pin inserts into a corresponding alignment hole on the shaft (picture DSC02412).

DSC02412 showing the alignment pin at 6:00 on the shaft.

DSC02440  The shaft is assembled  to the motor using six M5 x 0.8 - 16mm cap head bolts

DSC02440 Addition of a typical adapter plate (see below) using four M8 1.25 - 25mm cap head bolts.

DSC02443 The threaded holes of the mounted adapter plate allows for further attachment of the equipment.   

Different adapter plates are currently available and two examples are shown below.  

DSC02433 Adapter side facing the motor (2019-101-111 C).  NetGain part number IMP193-AP5.  This mates to SAE A Pumps.

DSC02435 Adapter side of  the IMP193-AP5 adapter that faces the "transmission".

DSC02431 Side of the IMP193-AP3 adapter side facing the motor (106).  NetGain part number IPM193-AP3.  This mates to SAE B Pumps.

DSC02438 side facing "transmission" or SAE This mates to SAE A Pumps.

DSC02416 rear face of the Micro 880.  The dust cap in the center can be removed and a custom shaft fabricated to allow for two motors to be used together.
