Novak Brushless Motor: Drift Spec Motor (55-3074M-1 Rev.1) - Manual (Page 2)

MOTOR TIMING ADJUSTMENT
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-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)
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. CONNECT MOTOR SENSOR HARNESS
• Determine the best routing in vehicle for the motor’s sensor
harness--securing sensor harness to the motor power wires with a
tie-wrap can provide a good location & also act as a strain relief.
• Connect one end of the harness to the ESC & the other end
to the motor’s sensor harness connector located on the back
endbell. Be sure the plug on the end of the harness inserts all
the way into the sensor harness connector--the plug & connector
are keyed and will only go together one direction.
INSTALLATION INSTRUCTIONS
GEAR SELECTION (Important)
The Drift Spec Motor is factory timed for optimal drifting operation.
It is not recommended to change the motor timing.
If it is necessary to change the timing, loosen the three main screws
on the back endbell, rotate the back endcap to desired setting, and
re-tighten the screws--DON’T OVER-TIGHTEN.
Retarding the timing (rotating clockwise*) will reduce RPM range
& increase torque--this usually reduces current draw and lowers
operating temperatures.
Advancing the timing (rotating counter-clockwise*) will increase
motor’s RPM range, reduce its torque, and make it less efficient, plus
it will pull more current, resulting in higher operating temperatures.
EXCESSIVE TIMING CAN CAUSE STATOR DAMAGE.
MELTED STATORS ARE NOT COVERED BY THE WARRANTY!

Motor operating temperature is the ONLY
way to properly set the maximum vehicle gearing
The motor should be 140-150°F MAX at end of run!
Temperatures above 150°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 exces-
sive 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 for shorter high speed runs, but
continued usage will produce excessive ESC & motor heating.
OVERHEATING -- WARNING !
The Novak Drift Spec Motor when used properly should not have an
issue of over-heating. However extended runtimes, gearing, vehicle
performance, and track conditions, can lead to overheating.
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.
Refer to below section regarding monitoring the temperature of your
motor to prevent overheating and damage.
Damage caused by excessive overheating WILL NOT be covered
under the product’s factory warranty.
