The High-Velociti GTB Racing Brushless Systems
2 NEW RACING BRUSHLESS SYTEMS
The newest brushless motor systems from Novak are fast, powerful, and designed to race. In fact, they 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). Each system includes Novak’s premier GTB Programmable Racing Brushless/Brush Speed Control factory-wired to either a Novak Velociti 5.5R Racing Brushless Motor (Brushless System part #3002), or a Novak Velociti 6.5R Racing Brushless Motor (Brushless System part #3003).


INTRODUCING NOVAK’S NEW GTB RACING ESC
The speed control used for both of the new systems, the GTB Racing Programmable Brushless/Brush ESC, is packed full of features. 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: Velociti 5.5 Racing (5 1/2-turn), Velociti 6.5 Racing (6 1/2-turn), SS5800 (8 1/2-turn), and SS4300 (10 1/2-turn).

The GTB is also programmable with a user-friendly interface, including 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.

The GTB uses exclusive lightweight MOSFET technology. These MOSFETs have the lowest ‘RDS On’ value, which allows the speed control to have the highest power density. The GTB uses more than twice the number of MOSFETs as the GTX, Novak’s competition ESC, making it the ultimate speed control for brushed and brushless motor performance

Like the GTX, the GTB includes all of the extra performance-enhancing components required for world-class racing, including a factory-installed heat-sink and cooling fan. Other convenient features include 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 (#1710), or as part of one of the new brushless systems.

INTRODUCING NOVAK’S TWO NEW VELOCITI BRUSHLESS RACING MOTORS
With over 5 years experience developing and manufacturing sensored brushless motors, Novak introduces the Velociti Racing Brushless Motors. Novak’s Velociti-series brushless motors are available in both 5 1/2-turns (#3405) and 6 1/2-turns (#3406), and are compatible with the Novak GTB Programmable Racing Brushless/Brush ESC.

The Velociti brushless motors feature a higher-strength magnet for top racing performance, and an oversized front bearing for increased load handling and bearing life. Like the Novak SS-series motors, the Velociti motors are specifically designed for R/C vehicles, are sensor-based for excellent starting torque 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.

The motors can be purchased individually (#3405 and #3406), or as a system with the GTB ESC (#3002 and #3003). [Please note, the Velociti-series brushless motors are not for use with Novak’s Super Sport ESC. The Super Sport and Super Sport Plus ESCs are rated for use down to 8 1/2 turns brushless.]

INTRODUCING NOVAK’S TWO NEW RACING BRUSHLESS SYSTEMS
Novak’s two new brushless systems include the new GTB Programmable Racing Brushless/Brush ESC, and either Novak’s new Velociti 5.5R Racing Brushless Motor (Brushless System #3002), or Velociti 6.5R Racing Brushless Motor (Brushless System #3003). A GTB System provides a better value to the customer as everything is installed and ready-to-go, with the bonus of additional savings over purchasing the motor and speed control individually. Because the Velociti motor was specifically developed for the GTB, and the entire system is factory-tested, racers can be assured that the GTB System will provide optimum performance. If you’re looking for a competitive, out-of-the-box, ready-to-race brushless system, the GTB Brushless System is the way to go.

又是大片英文～

能多介绍一下吗？相当有兴趣啊,可恨英文水平有限

晕，哪里有钱啊，我要打劫。

真的让爱小车说中了，RC这东西总是有更好的更新的东西出来。只是时间比预想的要晚一些。感觉RC更像一种时尚消费。无论是车架，还是设备新东西总是层出不穷。不过这样一来反而让出手谨慎的玩家持币观望了。

On-Resistance: 0.00040 ohms (per each phase -3); 0.00013 ohms (brushed mode)
无论无刷还是有刷，内阻都做到最小了

对无刷来讲，内阻还是不够小。估计跑它自己的5.5R还是会发热。对有刷来讲，内阻确实是足够小了。理论上，这个内阻已经接近导线的内阻了。如果用差一点的导线，直接短路电源＋和马达－，没准电线烧了，电调还没有事呢。

可以兼容SS5800！不错啊。房车玩BRUSH，越野玩BRUSHLESS..

以下是引用shouldbe在2005-5-29 22:16:34的发言：

ＧＭ今年也推出了新款的无刷电调连续工作电流有８０Ａ但是没有公布内阻，这个电调也是两用的有刷可支持到３.５Ｔ无刷可支持到５Ｔ．其实ＧＭ应该算是较早推出车用无刷的厂商了，其实力不可小视，值得期待
