Latest from Novak:

Four-pole motor advocates rejoice! The Novak 4PHD Heavy-Duty 4-Pole 4WD Short-Course Brushless Motor has arrived. The 4PHD is Novak’s 4-pole, 12-slot motor developed specifically for the high power demands and extreme running conditions seen by today’s popular 4X4 short course racing and extreme bashing. The 4PHD packs the punch of larger 550-size, 2-pole motors, and offers drivers the instantaneous throttle response achieved by 4-pole motors. The 4PHD is available in a 4600 kV rating, has an ultra-duty Neodymium rotor that is Kevlar-wrapped and rides on high-RPM ABEC 5 ball bearings treated with Novak’s Speed Lube premium bearing oil. The 4PHD brushless motor is perfect for today’s poplar 4X4 short course trucks from Durango, Traxxas, Associated, Techno, Team Losi, and more. If you're looking for a high-powered motor ready to take the abuse you dish, then look no further than Novak's 4PHD Heavy-Duty 4-Pole 4WD SCT 4600Kv Brushless Motor. Racers and basher's agree, the Novak 4PHD should be called "Dr. Power".

4-Pole Vs 2-Pole

What is the difference between a 4-pole and a 2-pole motor? More magnetic poles on the rotor, and more coils in the stator mean the motor is suited for hard acceleration and heavier loads. While the 2-pole motors, such as the Ballistic 550, thrive in high-RPM ranges, 4-pole motors will be superior in the flat-out acceleration race and constant low-to-mid RPM pulls. 4-pole motors thrive in heavier rigs, and typically run better on smaller tracks with lots of short acceleration requirements. The 4PHD is not your standard 540-size 4-pole motor! It is slightly longer and packs an extra punch while remaining more compact than a 550-sized motor. It’s the best of both worlds!

Pure Sensor-Based Design

Sensor based motor technology has been the mainstay of all competitive racers and teams. The speed control constantly knows exactly where the motor's rotor is, and can deliver extremely smooth and controlled response. The motor does exactly what you tell it, exactly when you tell it. You cannot be more connected to your throttle then you are with Novak 100% pure, sensor-based motor firing.

Heavy-Duty and Ready to Race

The Novak 4PHD motor’s heavy-duty design is built for the demands of 4X4 SCT driving.

  • Complete coverage heat sink– the motor’s can is precision CNC machined with heat sinking to provide maximum cooling
  • Pre-wired with 12AWG– multi-colored and ready to install with quality gold-plated, quality copper bullet plugs
  • Mounting options– 2 pairs of standard 3mm mounting holes, and 1 pair of extra heavy-duty 4mm mounting holes
  • High RPM bearings– ABEC 5 high RPM bearings are installed and treated with Novak’s exclusive Speed Lube premium bearing oil to extend life and increase RPM
  • Kevlar-wrapped rotor- for maximum reliability and performance
  • Keep the dirt out– rubber gaskets and a closed motor design will help keep the dust and dirt out of your motor
  • Heavy-duty shaft– ready for hard-core usage, the output shaft is 5mm


The Novak 4PHD brushless motor is compatible with the following Novak speed controls as well as other sensored or sensorless speed controls that can handle 4-pole motors with Kv of 4600.
