Novak Velociti 7.5R brushless motor

FOUR VELOCITI BRUSHLESS MOTORS…FROM FAST TO FASTER!
Irvine, CA – February 9, 2006 — The next installment in Novak’s Velociti-series brushless motors is the Velociti 7.5R (#3407). The 7.5-turn, sensor-based brushless motor is ideal for off-road applications that require less than maximum power for low traction settings, yet requires an ultra-smooth throttle response. The addition of the Novak 7.5-turn motor, along with the January release of the 4.5-turn motor, brings the number of Velociti motors to four!

The number of GTB/Velociti systems is also growing with Novak’s introduction of the GTB/Velociti 4.5 Racing Brushless System (#3001) and the GTB/Velociti 7.5 Racing Brushless System (#3007). Novak’s Velociti 4.5R Racing Brushless Motor (#3404) is Novak’s fastest motor to date, and the GTB/Velociti 4.5 Racing Brushless System has unbeatable brushless performance for competition touring cars.

GTB/VELOCITI BRUSHLESS SYSTEMS
Novak’s GTB/Velociti systems include all of the extra performance-enhancing components required for world-class racing, making them ready-to-race straight out of the box (nothing extra to buy or install). Because the Velociti motor was specifically developed for the GTB, and the entire system is factory-tested, racers can be assured that the GTB/Velociti system will provide optimum performance.

VELOCITI BRUSHLESS MOTORS
All Velociti brushless motors feature a higher-strength magnet for top racing performance, and an oversized front bearing for increased load handling and bearing life. The Velociti motors are specifically designed for R/C vehicles, are sensor-based for excellent braking and low-speed driveability, have low cogging, provide longer run-times than brushed motors, and meet all ROAR specifications. Additional features include direct-solder wiring tabs, locked rotor protection, thermal overload protection, and a virtually maintenance-free design.

To see which motor is best suited for you, see below:

#3404/#3001 Velociti 4.5R Ideal for competition touring cars and faster than the Velociti 5.5R

#3405/#3002 Velociti 5.5R Ideal for competition touring cars and high-traction off-road applications

#3406/#3003 Velociti 6.5R Ideal for off-road and low-traction applications and faster than the Velociti 7.5R

#3407/#3007 Velociti 7.5R Ideal for off-road and low-traction applications

GTB RACING BRUSHLESS/BRUSH ESC
All Velociti-series brushless motors are compatible with the Novak GTB Programmable Racing Brushless/Brush ESC so there is no speed control to update. This versatile ESC can be used with either brushless or brushed motors, has no brushed motor limit, and is compatible with all Novak 540-size sensored brushless motors, including the Velociti-series, as well as Novak’s SS-series (SS5800 [8 1/2-turn], and SS4300 [10 1/2-turn]).


The programmable GTB ESC has a user-friendly interface that includes 4 different color status LEDs that make programming extremely easy. The brushless mode has 4 adjustable parameters, including Minimum Brake, Drag Brake, Deadband, and Minimum Drive. The brushed mode is fully programmable with all of the adjustments of the brushless mode, plus adjustable Drive Frequency.

Other key features include the newest state-of-the-art MOSFET technology, a factory-installed heat-sink and cooling fan, One-Touch Set-Up, direct-solder wiring tabs, and a replaceable input and switch harness. It’s also equipped with Thermal Overload Protection and a water-resistant case. The GTB can be purchased individually, or as part of one of the new brushless systems.

The GTB/Velociti 4.5R system is scheduled to ship mid-February 2006. The Velociti 7.5R motor and GTB/Velociti 7.5R system are scheduled to ship end of February 2006. Part numbers and list prices for the new Velociti brushless motors and the new GTB/Velociti brushless systems follow:
