WarP 7™ & TransWarP 7™

These motors have a 7.25" frame diameter. They are series wound brushed DC motors. Both motors have double ended shafts. Our WarP 7™ motor has been designed for use in dual motor applications and to ease the conversion process for people who want dual motors and/or direct drive applications. These motors have many unique features that set them apart from any other brushed DC EV motor currently manufactured.

Unique advantages of WarP 7™ & TransWarP 7™ Motors:

  • Timing can be adjusted to CWDE or CCWDE(from the normal Neutral).
  • The WarP 7™ Drive End (DE) shaft and the Commutator End (CE) shaft are 1.125" in diameter with a 1/4" keyway.
  • The WarP 7™ is not the typical 1.125" single-keyed type, but rather a hefty 1.370" shaft with a 32-tooth involute spline that is identical to the tail shaft spline of a Turbo 400 transmission. The Commutator End (CE) shaft is 1.125" in diameter with a 1/4" keyway that will match with the WarP 7™ Drive End (DE) shaft.
  • These motors have brush wear indicators and a temperature snap switch.
  • They have high efficiency fans and massive commutators and brushes.
  • The TransWarP 7™ motor uses an optional "shorty" tail shaft housing from a Chevrolet Turbo 400 transmission fitted to the drive end-bell (may be ordered with or without housing!) This motor was originally designed to be coupled directly to a drive shaft!
  • We have added double wide bearings on the drive end of the TransWarP 7™ motor, and we've added grease fittings (as you now have a slip-yoke assembly...). We use the industry standard 1350 universal, so you can easily adapt it to any manufacturers drive shaft!
  • We also made the commutator end shaft of the TransWarP 7™ motor the same diameter as the drive end of a typical WarP 7™ - just in case you wanted to connect 2, 7" motors together!

WarP 8™

These motors have an 8" frame diameter. They are series wound brushed DC motors. This motor can be purchased as a single or double ended shaft motor. Our WarP 8™ motor is basically a twin to the ADC 8" motor (203-06-4001A), but at a better price point. As a convenience to our customers we have duplicated the mounting bolt pattern to allow our clients to utilize existing mounting plate adapters.

Delivery Time: Special Order

Unique advantages of WarP 8™ Motors:

  • It is an 8" diameter series wound DC motor with a double ended shaft.
  • The motor utilizes large style comm's and brushes.
  • The comm's are key-locked onto the drive shaft -- reducing the likelihood of lifting any commutator bars.
  • Class "H" insulation is used throughout the motor
  • The drive shaft and tail shaft have standard keyways cut into them
  • The drive shaft comes with a pilot bearing hole and a 5/16 - 18 mounting hole
  • The world renowned "White Zombie" (built by John Wayland) originally used two of our WarP 8™ motors. This car is the world's quickest and fastest "Street Legal Electric Vehicle". John has since switched to dual ImPulse 9™ motors.

The Essentials:

  • Type - Series wound DC
  • Diameter - 8"
  • Length - 14.42" (face-face)
  • Weight - 106 lbs.
  • HP - 28 (Continuous @ 144V)
  • RPM - 5,800
  • Torque - 70 lb-ft @ 463 Amps

ImPulse 9™ & TransPulse 9™

These motors have a 9.25" diameter frame. They are series wound brushed DC motors with a double ended shaft (or single ended as desired) and are pre-drilled to allow for brush advance (favored timing) in either neutral, advanced CWDE or advanced CCWDE (standard). Our ImPulse 9™ Motor shares many of the internal components found in our WarP 9™ Motor, but has the mounting pattern and pilot to match 8" motors (Model 00-08259 & Model 00-08269, Model 00-08249 does NOT match ADC 8" and is no longer a stocked item!).

Delivery Time: From Stock

Unique advantages of ImPulse 9™ & TransPulse 9™ Motors:

  • The commutator bars are more securely attached to the arbor, so they will be less likely to lift.
  • The laminations are all keyed onto the armature shaft to prevent movement - most laminations are simply pressed onto a round shaft.
  • 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.
  • We have duplicated the ADC 8" mounting bolt pattern allowing clients to use preexisting mounting adapters (Model 00-08259 & Model 00-08269).
  • Model 00-08249 does NOT match the ADC 8" mounting pattern, but rather matches the ADC 9" bolt pattern.
  • 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 Essentials:

  • Type - Series wound DC
  • Diameter - 9.25"

  • Weight - 129 lbs.
  • HP - 30 (Continuous @ 144V)

WarP 9™ & TransWarP 9™

The WarP 9™ motor is similar to the ADC 9" motor, but with numerous improvements. It is a 9.25" diameter, series wound, brushed DC motor with a double ended shaft (also available as single-ended). Of the most notable changes, we have a larger commutator and utilize the larger style brushes specially formulated for EVs.

Delivery Time: From Stock

Unique advantages of WarP 9™ & TransWarP 9™ Motors:

  • 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.
  • Addition of temperature thermistor: This will allow the motor temperature to be 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.
  • The TransWarP 9™ motor uses an optional "shorty" tail shaft housing from a Chevrolet Turbo 400 transmission fitted to the drive end-bell (may be ordered with or without housing!) This motor was originally designed to be coupled directly to a drive shaft!
