ImPulse 9

72-156V, 400A, DC

Advanced Timing

NetGain EV Motors

This is a 9.25" diameter, series wound DC motor with a double ended shaft and is pre-drilled to allow for brush advance in either Neutral, advanced CWDE or advanced CCWDE (standard). Our ImPulse 9 ™ Motor share 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!). There is also a single ended shaft version of this motor - 00-08269.


The commutator 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 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.

Dual Wafer Helwig Carbon Brushes:

Extra large brushes are designed for the high voltages and currents used by today’s electric vehicles. Our motors use specially formulated, high performance brushes manufactured exclusively for our motors by Helwig Carbon. The split brush design offers longer brush life and better commutation. Four wires go into each high performance brush (two per wafer) versus the more common single wire per brush.
