1. NO MOTOR CAPACITORS & SCHOTTKY NEEDED

Novak brushless motors do not need motor capacitors or external

Schottky diodes--Schottky diode usage will damage ESC.

2. CHECK MOTOR SCREW LENGTH & INSTALL MOTOR

• Insert the motor mounting screws that came with your vehicle

through the motor mounting plate.

540 & 550-size motors need

no more than 1/8” of screw extending past the vehicle’s mounting

plate (2-4mm)--Too little can strip the motor’s threads, too much

will cause internal motor damage & will void warranty.

• Attach motor to vehicle’s motor mount using one of the sets of

threaded mounting holes--

select a mounting position that keeps the

solder tabs clear of conductive surfaces like aluminum or graphite.

3. INSTALL PINION GEAR (see GEAR SELECTION on back)

Install pinion on motor and test fit in vehicle to align pinion and

spur gears. Tighten pinion’s set screw on the flat of motor shaft.

4. ADJUST MOTOR FOR PROPER GEAR MESH

• Adjust the motor position for proper amount of free play. You

NEED to have a small amount of play between the pinion gear

and the spur gear (about the thickness of piece of paper)--check

the free play at several positions around the spur gear to

ensure a proper mesh

(just in case the gears are out of round).

MAKE SURE THE PINION/SPUR GEAR MESH IS NOT TOO TIGHT!

If gear mesh is too tight, motor shaft breakage can occur.

• Tighten motor mounting screws--Avoid using excessive force,

as the threaded holes in motor could become stripped.

5. SOLDER 540/550 MOTOR WIRES & CONNECT SENSOR HARNESS

• Determine the best routing in vehicle for sensor harness & power

wires. Prepare ends of motor power wires by stripping 1/8-

1/4” of insulation from end of wire. Tin wire ends with solder.

Lay tinned end of the wire flat on the solder tab and solder wires

to proper tabs of the motor (see photo below). Apply heat with

soldering iron to the power wire and solder tab--begin adding

solder to tip of iron and to wire--

Add just enough solder to form a

clean & continuous joint from the solder tab up onto the wire.

WARNING: Be sure no wire strands have strayed to an adjacent solder tab--this

will cause short-circuiting, damage electronics, & void product’s warranty.

Be sure to solder wires

to matching tabs at
ESC & Motor

(A/B/C)

IMPORTANT NOTE: DO NOT OVERHEAT SOLDER TABS

Prolonged/excessive heating of solder tabs will damage PCB & void warranty.

Should any of the 26G Teflon wires pull out of the motor’s sensor

harness connector, re-insert them in the connector’s appropriate

slot as shown below. There is a small plastic tab that grabs a small

raised barb on the back of the metal socket crimped onto the Teflon

wire’s end. Check the plastic tab to make sure it has not deformed

excessively before inserting the socket into the plastic connector

housing with the barb toward the plastic tabs.

SENSOR HARNESS WIRING

SENSOR HARNESS WIRING

Motor operating temperature is the ONLY

way to properly set the vehicle gearing

The motor should be 160-175°F MAX at end of run!

Temperatures above 175°F will weaken the magnet & may

melt the coils! This voids warranty & can damage ESC!

Change the gearing to avoid overheating.

Because of the potential danger of overheating, ESC/motor damage & failure,

you must start with VERY small pinion sizes and check ESC & motor

temperatures at multiple times throughout a run. This is the only way to

ensure that you are not causing excessive heating.
If ESC & motor temperatures remain low & stable, you can slowly increase

the pinion size while again monitoring the temperatures to determine the safe

gearing for your vehicle, motor, and climate/track conditions. Because these

variables can change or be modified,

you MUST continually monitor ESC &

motor temperatures to protect your electronics from damage.

If you do not change gearing after switching to brushless, you will be

over-geared and will have slow acceleration & excessive temperatures!

Because of the broad power band of brushless, you can go 1-2 teeth higher

pinion than the above recommendations for more top speed, but remember

any higher will produce excessive ESC & motor heating. Check the motor’s

operating temperature after making any gearing adjustments--motors are

designed to operate from 160ºF-175ºF maximum.

Crawler Brushless Motors

When properly geared for use with gear reduction transmissions found in rock

crawling vehicles, your brushless crawler motor and ESC should not get very

hot--if you notice excessive temperatures, check motor & drive train for free

operation or adjust gearing to lower temperature.

Three-80 Micro Pro Brushless Motors

A safe starting point for gearing is 3-5 teeth smaller than the stock pinion gear

that came with your micro vehicle. When properly geared, your Three-80

system should not get excessively hot--if you notice high temperatures, check

motor & drive train for free operation or adjust gearing to lower temperature.

550-size (high-voltage) Brushless Motors

Novak 550 motors should be geared based on the end-of-run motor & ESC

temperatures--adjust gearing so the temperatures do not exceed 160-170°F.

OVERHEATING -- WARNING

!

Due to the inherent nature of racing, timing advance speed controls,

brushless motor tolerances/settings, vehicle performance, and track

conditions, it has become virtually impossible to provide accurate

installation and operation recommendations that will allow you to use

these motors at their highest performance levels without the potential

for unwanted damage.
You must, use extreme caution when setting up these electronics and

carefully test your application to avoid overloading and overheating

either the speed control or the motor.
These are racing electronics used in racing conditions, and therefore

damage as the result of excessive overheating WILL NOT be covered

under the product’s factory warranty.
