Indeed, in the early days, IC engine engineering was less advanced than electric motor engineering.. In addition to being one of the two first hybrid vehicles, and the first parallel hybrid vehicle, the Pieper was undoubtedly the first electric starter.. In the French case, the hybrid design was used to extend its range by recharging the batteries. Other hybrid vehicles, both of the parallel and series type, were built during a period ranging from 1899 until 1914.

Stepper motor

tailieu.vn

A stepper motor (or step motor) is a brushless, synchronous electric motor that can divide a full rotation into a large number of steps. The motor's position can be controlled precisely without any feedback mechanism (see Open-loop controller), as long as the motor is carefully sized to the application.

Brushed DC Motor Fundamentals

tailieu.vn

As the motor turns, the windings are constantly being energized in a different sequence so that the magnetic poles generated by the rotor do not overrun the poles generated in the stator. This switching of the field in the rotor windings is called commutation.. Unlike other electric motor types (i.e., brushless DC, AC induction), BDC motors do not require a controller to switch current in the motor windings. Instead, the commutation of the windings of a BDC motor is done mechanically.

Many of the concepts presented here apply to most motor types, since all motors are constructed of similar materials and all produce the same output, namely, torque.. To put these motor types into perspective, it is useful to show where they fit in the overall classification of electric motors as shown in Fig.. The other motors shown in the figure are not considered in this text. The most common motor shape is cylindrical, as shown in Fig.

The gasoline motor is a 67 horsepower, 1.0 liter, 3-cylinder engine, which serves as the primary motor in the vehicle. Unlike Toyota, Honda develops their hybrid vehicles to be lighter and use the gasoline powered engine as the primary engine, with the electric motor as a supplement. The electric motor in the Insight is a 10 kW motor/generator that produces 13 horsepower. The major advantage of the Insight over other hybrid vehicles in fuel efficienc y is its low drag coefficient.

Hybrid electric systems can be broadly classified as series or parallel hybrid systems [9–12]. 21.11 and 21.12, respectively. In EV, the electric motor behaves exactly in the same manner as in a series hybrid. Therefore, the torque and power requirements of the electric motor are roughly equal for an EV and a series hybrid, whereas they are lower for a parallel hybrid.. Figure 21.13 depicts the conventional electrical power distribution system architecture for hybrid electric vehicles.
