NOVAK VELOCITI 5.5R Manual
• WATER & ELECTRONICS DON’T MIX Never allow water, moisture,
or other foreign materials to get inside motor, or on PCBs.
• CHECK MOTOR SCREWS Remember to check all motor
screws for loosening. The 3 main 4-40 socket head screws on
the shaft end of the motor may become loose after a few
runs of the motor, and will need to be tightened.
• NOVAK MOTORS WITH NOVAK ESCs ONLY Velociti series
of motors are designed for use with sensor-based Novak
Brushless ESCs Only! Only use Velociti Novak sensored motors
with Novak Brushless speed controls rated to handle down to
the the number of turns of the motor.
Do NOT use Velociti motors with Super Sport or Super Sport Plus ESCs.
• INSULATE WIRES Always insulate exposed wiring with heat
shrink tubing to prevent short circuits.
• NO SOLVENTS Exposing the motor to any type of solvents
can damage the exposed material.
• Solder power wires at motor by stripping 1/8-1/4” of
insulation from the end of the motor power wire (14G).
Tightly twist strands of wire, lightly tin, and insert into proper
solder tab’s hole (tabs are identified by lettering that is
engraved in the end cap of the motor--see photo below). Use
soldering iron to apply heat to exposed wire that is extending
past bottom of PCB, and begin adding solder to tip of
soldering iron and to wire. Add just enough solder to form a
clean & continuous joint from the plated area of solder tab
up onto the wire. Use side cutters to trim remaining (now
soldered) wire from below the solder tab (about 1/16” above
PCB)--
make sure no strands of wire have strayed to an adjacent solder tab
as this can result in short-circuiting & damage to the electronics, which
will void the product’s warranty.
Be sure to solder wires
to matching tabs at
ESC & Motor
(A/B/C)
• Note: Power wires can also be soldered flat onto the PCB solder tabs.
Strip 3/16-1/4” of insulation from the end of the new wire.
Tightly twist strands of wire, and tin with solder. Lay the
stripped & tinned end of the wire flat on the PCB solder tab
and use soldering iron to heat the end of the wire, and add
solder to form a clean solder joint between the wire and the tab.
IMPORTANT NOTE: DO NOT OVERHEAT SOLDER TABS
Prolonged/excessive heating of solder tabs will damage PCB.

PRECAUTIONS
WIRING MOTOR TO ESC
1. MOTOR CAPACITORS & SCHOTTKY NOT NEEDED
Novak brushless motors have built-in motor capacitors, and
like all reversible ESCs, does not use an external Schottky
diode--Schottky diodes damage reversible ESCs.
2. CHECK MOTOR SCREW LENGTH
Insert the M3 motor mounting screws that came with your
vehicle through the motor mounting plate in vehicle. You
need to have no more than 1/8” of screw extending past
the vehicle’s mounting plate (2-4mm). Too little can strip
the threads in the end bell, and any more will cause short-
circuiting/damage inside the motor & will void warranty.
3. INSTALL PINION GEAR (see GEAR SELECTION on back)
Install pinion gear on motor and position set-screw over flat
on end of shaft. Test fit motor in vehicle to align pinion and
spur gears, then tighten pinion gear on shaft.
4. INSTALL MOTOR IN VEHICLE
• Determine the best routing for sensor harness & motor
power wire. Some off-road cars may require routing hte
motor power wires through the shock tower--refer to the
“WIRING MOTOR TO ESC” section.
• Using the M3 motor screws that came with your vehicle,
attach motor to vehicle’s motor mount using one of the
three sets of threaded mounting holes--select a mounting
position that will avoid short-circuiting of solder tabs on conductive
surfaces such as aluminum or graphite.
• Check gear mesh for proper amount of play. You want to
have a small amount of free play between the pinion and
spur gears (about the thickness of piece of paper)--check
free play at several positions around the spur gear.
• Avoid using excessive force when tightening motor screws,
as the threaded holes could become stripped.

SUPER-FLEX SILICONE 14G WIRE
Novak Super-Flex 14G wire in kits #5500 (36”red/36”black) and
kit #5508 (2 each of 9”red/black/blue/yellow/orange).
VELOCITI MOTOR BEARINGS & FRONT END BELL SET
After extensive use, the ball bearings in the motor may need
replacement. Velociti front end bell with bearing factory-installed
& rear bearing are available in Novak kit #5920.
VELOCITI MOTOR REPLACEMENT ROTOR
After extensive use, the motor’s rotor may need replacement
due to loss of magnetic strength
(normal after extended use)
.
Replacement Velociti rotor available in Novak kit #5921.
ACCESSORIES
SENSOR-BASED DESIGN BENEFITS
• Constant Rotor Position Knowledge
Because the speed control and motor are continuously
synchronized via the motor harness, the sensor-based system
can provide instantaneous throttle response and smooth
transitions from neutral to drive--NO COGGING.
• Smooth & Controlled Low Speed Driveability
Always knowing what angle the rotor is at is key to smooth
acceleration without delivering abrupt and uncontrolled
bursts of power.
• Strong/Consistent Brakes & Starting Torque
Rotor position knowledge results in consistent starts & stops,
without hesitation or inconsistent lag times before
acceleration or braking--this translates to consistant lap times.
• Locked Rotor & Thermal Protection
Position & temperature sensors inside motor provide
unparalleled thermal protection for your investment, letting
you to run pack after pack without worrying about
overheating the motor, ESC, or magnets.
