Novak Brushless Motor: 4PHD Heavy-Duty 4-Pole BL Motor (55-3510M-1 Rev.1) - Manual

PRECAUTIONS
NEVER FREE-REV THE MOTOR!
Free-running your brushless motor in a
no-load condition can result in rotor failure
and ESC transistor damage. This will void
the product’s warranty!
• WATER & ELECTRONICS DON’T MIX Never allow water,
moisture, or other foreign materials to get inside motor, or on
the ESC’s PC board.
• NOVAK MOTORS & ESCs FOR BEST RESULTS Use Novak
sensored motors with Novak Brushless ESCs for best
performance & protection. Only use motors with the proper
Kv to match ESC’s rating.
• DO NOT OVERHEAT THE MOTOR Temperatures above 160 ° F
will weaken the magnet and may melt the coils. This voids the
warranty and can damage the ESC.
• INSULATE EXPOSED WIRES Use heat shrink tubing to prevent
shorts. Refer to ACCESSORIES for Novak heat shrink kits.
• NO SOLVENTS Do NOT expose the motor or electronics to
any type of solvents.
• SET GEAR MESH PROPERLY Too tight of a gear mesh can
result in motor pinion shaft breakage--be sure to adjust the
gear mesh properly.
• NO MOTOR CAPACITORS & SCHOTTKY DIODE Novak
brushless motors do not need motor capacitors or external
Schottky diodes. Schottky diode usage will damage ESC.

Included with the 4PHD motor are Novak’s low-loss, high-current,
gold-plated bullet connectors. Both connector sides are included if
you wish to install on your motor and/or speed control.
1. Insert the motor mounting screws that came with your vehicle
through the motor mounting plate. Novak 4PHD 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
and will void warranty.
2. Attach the motor to the vehicle’s motor mount using one of
the sets of threaded mounting holes (M3x0.5 or M4x0.7).
Select a mounting position that keeps the solder tabs clear
of conductive surfaces like aluminum or graphite.
STEP 1- INSTALL MOTOR
1. Determine the best routing in the vehicle for the motor’s
sensor harness. Securing the sensor harness to the motor
power wires with a tie-wrap can provide a good location and
also act as a strain relief. Novak offers several sensor harness
lengths for various installations (Novak #5351-5354)
2. Connect one end of the harness to the ESC and the other end
to the motor’s sensor harness connector located on the back
endbell (refer to figure).
Be sure the plug on the end of the
harness inserts all the way into the
sensor harness connector. The plug and
connector are keyed and will only go
together one direction.
Note: If any of the teflon wires pull out
of the motor sensor harness connector,
refer to the SENSOR HARNESS WIRING
section on back.
1. Install pinion gear on the motors output shaft and test fit in
vehicle to align pinion and spur gears.
Refer to GEAR SELECTION (on the back) for additional
information on selecting the proper pinon gear.
2. Tighten pinion’s set screw on the flat of motor shaft.
3. Adjust the motor position for proper amount of free play.
It is important 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 PINION/SPUR GEAR MESH IS NOT TOO
TIGHT! IF GEAR MESH IS TOO TIGHT, MOTOR SHAFT
BREAKAGE CAN OCCUR.
4. Tighten motor mounting screws. Avoid using excessive force,
as the threaded holes in motor could become stripped.
