−
−	~~The Concept Car engine is based on an air-cooled sensorless brushless electrical motor, which is presented in Figure 2.1.~~
−
−	~~Each part of the engine presented in Figure 2.1 is described in the following:~~
−
−	* The motor is a 1930/9 from Lehner Motoren and its characteristics are shown in Figure 2.2. [LM09].
−	* The engine control is a Power JAZZ from Kontronik. Its characteristics are presented in Table 2.1 [Kon09].
−	* The power is supplied by an accumulator with a nominal voltage of ~21V and the ability to sustain a permanent discharge current of at least 80A. The actual type and internal construction of the accumulator is irrelevant, as long as these specifications are met. Currently a 5S1 LiPo accumulator is used.
−	* The 5-6V supply voltage of the steering servo (max. 3A) is generated by a high-efficiency step-down voltage converter.
−
−	~~Figure 1.2 presents the Motor Characteristics.~~
−
−	~~Due to its sensorless nature, the engine tends to stutter when the car is pulling off.~~

−	~~====1.1.2. Radio Control====~~
−	The ConceptCar is remotely operated via a standard 2 channel 27MHz radio transmitter system. The channels are used for throttle and steering data. The radio receiver generates a 50Hz PWM signal with 5% to 10% duty cycle.
−
−	~~====1.1.3. Steering System====~~
−	The steering system has simple mechanics; a servo motor sets the steering angle. Within a range of ±30° the steering angle is set to (pulse – 1.5ms) * 1° / 0.018ms, where “pulse” denotes the length of a PWM pulse at a PWM frequency of 50Hz.
