do hybrid car electric motors have carbon brushes?

    Older designs for electric car motors use carbon brushes, and even today many hobbyist-built electric cars use brushed motors because of low cost and relative simplicity of design. Motor brushes of this type typically last for 80,000 to over 100,000 miles.

    However, virtually all new electric drive motors are of the AC type, which require no brushes. The motors are instead fed with rapidly pulsed current which creates rotating magnetic fields. Motor speed and power is controlled by varying the intensity and frequency of the current.

    GM's well-known EV1 electric car was one of the first electric cars to use this type of motor drive.

    No hybrid car electric motor does not have Carbon Brush in it . It is created in such a manner without a carbon brush it work more effective than brushed motor .

    Nope. Hybrids use brushless motors largely because they are more efficient than brushed motors. Brushless motors electrically commute the wiring via a specialized controller. This eliminates the frictional losses from the brushes. It also eliminates a wear item.

    Electric motor/generators are generally one of two types, either AC (Alternating Current) or DC (Direct Current) and those designations are indicative of the type of electricity that they consume and generate. Without getting into too much detail and clouding the issue, this is the difference: AC current changes direction (alternates) as it flows through a circuit. DC currents flows uni-directionally (stays the same) as it goes through a circuit. The type of current utilized is concerned mostly with the cost of the unit and its efficiency (An AC motor/generator is generally more expensive
