WarP 9 ™ Motor

Our WarP 9  motor is similar to the ADC 9" motor, but with numerous improvements. It is a 9.25" diameter, series wound DC motor with a double ended shaft. One of the most notable changes is a larger com and that it utilizes the large style brushes. Beginning with motors being manufactured in July, 2010 numerous enhancements are being added to our entire line of motors, some of which include:

  • 1/2”-13 diameter terminal studs: Increased from 3/8” diameter - bigger is better!
  • New brush composition: Handles higher voltages and currents – improves motor efficiency
  • New brush design: “split brush with pad” design handles higher voltages and currents – improves motor efficiency
  • Increased spring pressure: Spring pressure has been increased to allow improved commutation (note: This does NOT increase brush-commutator wear as might be suspected)! Higher spring pressures allow for increased commutation – which improves commutator wear over “bouncing brushes”.
  • Addition of optical RPM sensor hole: A 1/2”-20 hole is drilled and tapped into the DE for easy insertion and use of an RPM sensor. (further information will be provided on appropriate sensors and gauges (RPM, temperature) in the near future.)
  • Addition of temperature thermistor: This will allow the motor temperature to be monitored.
  • Removal of brush wear indicators: To the best of our knowledge, no one ever used this feature. As armature voltage was used for signaling it was difficult to adapt and use.
  • Improved fan: Increased air flow will allow the motors to run cooler and more efficiently. The 15- blade fan is a new casting that will make using the RPM sensor easier as well.
  • Drive End mounting holes changed from “blind holes” to thru holes. If the wrong length bolts were used it could damage the DE head. Care must still be exercised to ensure that the mounting bolts do not hit the fan blades!
  • Temperature snap switch and thermistor plug will use the same black plug that was previously used for the brush wear indicators and accepts 1/4”, flat spade connectors, but it will now be counterbored.
  • All of the above changes are being phased into production across ALL motors.

    The com bars are more securely attached to the arbor, so they will be less likely to lift. The drive shaft is bored for a pilot bearing and drilled & tapped for a 5/16 - 18 bolt. The tail shaft also has a 1/4 - 20 bolt hole to mount tach sensors or secure couplers and accessories. Again, we have duplicated the ADC 9" mounting bolt pattern allowing clients to use preexisting mounting adapters. Class "H" insulation is used throughout the motor. The drive shaft and tail shaft have standard keyways cut into them. This motor is also available at a better price point to end users.

    The maximum operating voltage of the WarP 9 is 170V to the armature. If the motor sees voltage higher than 170V for any period of time, it will arc incrementally worse as the voltage increases. The user can split the voltage of a 350V pack between two NetGain motors wired together in series. This will allow the maximum 170V to each motor, and they will both see the full amperage supplied by the controller.

    Amps are the larger source of heat buildup. High voltage will cause poor commutation (arcing) where high current will cause more heat buildup within the motor. So additional cooling will not offset any higher voltage, but it will allow for higher current over longer periods of time. Current ratings for the WarP 9 (with no external cooling) are shown below:


            2000 Amps for short periods (seconds) of time...

            500 Amps for 5 minutes

            250 Amps for 1 hour

            200 Amps continuous
