User manual NOVAK VELOCITI 5.5R

[. . . ] · 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. 55-3405-1 · Printed 8-2005 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. · 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. ACCESSORIES 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. [. . . ] 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. Be sure to solder wires to matching tabs at ESC & Motor (A/B/C) motor phase wire tab I. D. text · 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. · 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. GEAR SELECTION (Important) As a general rule when using the Velociti 5. 5R Brushless motor with 6 cells, start with a 3 tooth lower pinion gear than you would normally use with a low-turn brush-type motor. As a general rule when using the Velociti 6. 5R Brushless motor with 6 cells, start with a 2 tooth lower pinion gear than you would normally use with a low-turn brush-type motor. Because of the broad power band of brushless, you can go 1 to 3 teeth higher pinion than the above recommendations for more top speed, but remember that going with 3 or more teeth higher will produce excessive ESC heating. Be sure to check the operating temperature of the ESC after making any gearing adjustments--the GTB ESC is designed to operate comfortably from 160ºF-180ºF (warmer than typical brush-type ESC). MOTOR MAINTENANCE ·CHECK MOTOR SCREWS Check all motor screws for loosening at regular intervals, just like other hardware on your vehicle. Note: 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. Also check the 3 flat head screws securing the end cap on the back of the motor. ·CHECK MOTOR BEARING WEAR After extensive use, the ball bearings in your motor may need to be replaced. While the motor's closed design will keep out the majority of dirt & debris, some will eventually get in and wear will occur. If the shaft will not spin freely, you may need to replace the motor bearings (replacement Velociti front end bell with bearing factory-installed & rear bearing are available in Novak accessory kit #5920--If you do not feel comfortable changing the bearing and end bell on your own, please contact our Customer Ser vice Dept. A small drop of light oil on the bearings If you had a low turn modified brush-type motor in the vehicle before switching to the Novak Racing Brushless system, and you do not change gearing, you will be overgeared and the vehicle will have slower acceleration! Start within these final drive ratio ranges in the vehicle: 8. 75-9. 25 : 1 7. 75-8. 5 : 1 11. 5-12. 0 : 1 10. 5-11. 0 : 1 13. 0 : 1 12. 3 : 1 Velociti 5. 5R in Touring Cars (rubber tire) Velociti 6. 5R in Touring Cars (rubber tire) Velociti 5. 5R in Off-Road Buggies Velociti 6. 5R in Off-Road Buggies Velociti 5. 5R in Off-Road Stadium Trucks Velociti 6. 5R in Off-Road Stadium Trucks periodically can help extend bearing life--however, too much oil will attract dirt and will cause problems, so apply sparingly. ·CLEAN INSIDE MOTOR Periodically remove the front end bell of your motor, remove the rotor, and blow out the inside of the motor with comressed air. Be sure not to lose any small shim washers that may be on the ends of the rotor shaft & keep them in the correct location. Higher final drive ratios will give longer run time at the expense of top speed. Lower ratios will result in higher ESC temperatures--too low may result in overheating & thermal shut-down.
