#3525-3527 HV High-Voltage Brushless Motor with 5mm Shaft

The HV Pro Brushless System is made up of the rugged HV Brushless Motors with 5mm Shafts and specially designed HV Pro High-Voltage Brushless ESC that work seamlessly together to provide the ideal system for high-voltage applications. The HV Systems were specifically developed by Novak for R/C cars, and are ideal for monster trucks - such as the Traxxas® E-Maxx™, Traxxas® E-Revo™, HPI® E-Savage™ and Kyosho® Twin Force™-- converted electric 1/8-scale vehicles* and vehicles with massive power needs.

Novak's HV Pro Brushless Systems with 5mm Shafts are available in three motor winds:

  • HV Pro Brushless System 5.5T with 5mm Rotor (Kv=3,700; Watts=800) has superb control, and excels in racing and bashing applications (#3025).
  • HV Pro Brushless System 6.5T with 5mm Rotor (Kv=3,400; Watts=730) is the best all-around-motor with a great balance between power and run time. It also shines in racing and bashing applications (#3026).
  • HV Pro Brushless System 7.5T with 5mm Rotor (Kv=3,000; Watts=620) has incredibly smooth power delivery, making it the easiest to drive, and is recommended for users looking for the longest possible run times (#3027).

In addition to its already impressive features, including awesome starting torque, low-speed driveability, and no cogging for smooth acceleration and smooth braking, the HV Series of motors (#3525-3527) has been fitted with a rugged 5mm output shaft for maximum resilience and race life. The HV Series is ideal for monster trucks, converted electric 1/8-scale vehicles* and vehicles requiring massive power output. Additionally, the motors are sensor-based, so they always know the position of the rotor, which provides excellent starting torque and continuous synchronization for smooth, controlled low-speed driveability and consistent brakes. Simply stated, it means no uncontrolled bursts of power or delays! HV-Series of motors also features a shielded sensor cable with sheathed sensor wires and a completely rebuildable design.

For longevity of your system, it is recommended to use a 12-tooth pinion gear, such as Novak's 5mm 32-Pitch Steel Pinion Gears (#5152). The below table is recommended only for maximum gearing.

Completing the HV Pro Brushless System is the
fully programmable HV Pro ESC, which can accommodate 6-14 Ni-Cd/Ni-MH cells (7.2-16.8 volts) or 2S-4S Li-Po and can be wired for dual or single battery packs. This high-power, reversible brushless speed control is also easy to install and operate. The HV Pro uses the same screw pattern as the Traxxas® E-Maxx™, Traxxas® E-Revo™, HPI® E-Savage™ and Kyosho® Twin Force, making it convenient to install, and it includes a Power-Boost ESC Cooling fan kit and factory-installed motor heat sink for superior cooling. In addition, the HV Pro High-Voltage Brushless ESC includes many of the same great features found in high-quality Novak ESCs, such as One-Touch Set-Up, Thermal Overload Protection, a powerful BEC, Polar Drive and Digital Anti-Glitch circuitry and Smart Braking II.

Novak has also done away with the external Li-Po module with the inclusion of the built-in, auto-detect Smart-Stop Li-Po Cut-Off Circuitry**. When active, the Cut-Off Circuitry automatically switches to the proper Li-Po cut-off voltage for the connected battery packs, preventing the batteries from going below the critical safety voltage level.

In addition, the ESC includes black heat sinks for better heat transfer. You won’t mistake this high-voltage system with any other!

In addition to full programmability, Novak’s HV Pro High-Voltage Brushless ESC (#3221) has three throttle profiles – two with reverse and one with forward/brake. Each throttle profile has on-board programming for extreme versatility and unmatched customization for Minimum Brake, Drag Brake, Dead Band, Minimum Drive, Throttle Curve, Brake Frequency, Brake Disable, Motor Rotation and Li-Po Cut-Off. These programming features make operating an R/C car as easy as One-Touch set-up. Novak’s Throttle Curve adjustment allows drivers to tailor the throttle response, creating either a quick burst of power with the Linear Curve setting, or a smoother, controlled low-end power delivery with the Expo Curve setting.

5mm Mod 1 Hardened Steel Pinion Gears
5mm 32-Pitch Steel Pinion Gears

To mesh with the HV Brushless Motor’s rugged 5mm output shaft, Novak also offers two series of precision steel pinion gears. Novak’s 5mm Mod 1 Hardened Steel Pinion Gears (#5100-5110) are recommended for Novak’s 1/8-scale Conversion Kits (#5010-5019), and Novak’s 5mm 32-Pitch Steel Pinion Gears (#5152-5157) are recommended for powering monster trucks that use a 32-pitch plastic spur gear.

Like all Novak brushless systems, the brushless speed control and brushless motor are factory wired and tested together, so they are ready to “plug and play” straight out of the box.

The HV Pro ESC and motor contain Thermal Overload Protection circuitry to protect the system from overheating and damage. In fact, the ESC will only operate with the HV-Series or other brushless motors that have built-in thermal protection that follow ROAR guidelines. This sophisticated feature ensures a fun day at the track without the worry of overheating. For the complete list of compatible motors, click here.
