For Electric Motor Manufacturers

Efficient Development
of Electric Motors for Cars

When we talk about electric motors for cars, many people think of the electric motor “only” as a replacement for the combustion engine. However, an expanding number of electric motors are being used for a wide variety of functions that go far beyond main driving unit.

Electric motors for cars are used for following functions:

  • New auxiliary drives (such as oil and water pump)
  • Power steering motors
  • Brake motors
  • Air conditioning actuators
  • Comfort drives (seat adjusters, tailgate adjusters and side door openers)
  • Drives for window lifters, side mirrors, headlights, sunroof, sunshade and many other components

Even in these applications, choosing the right electric motor from the right manufacturer is crucial to increasing the overall competitiveness of one’s own product.

Electric motors for cars

Important factors for electric motors for cars are as follows:

Each electric drive must match the mechatronic product to offer the most efficient and optimum solution to the customer. Achieving an optimal interaction between the various components requires a deep knowledge of all relevant functions. A motor simply has to match the rest of the system in terms of quality to optimally enhance or optimize it.

It is exactly in this context that “off the shelf” electric motors (catalogue goods) rarely turn out to be the optimum for the customer. And there is no question that motor costs ultimately influence competitiveness.

Not all electric motors are the same:

There is enormous potential for optimization here

In mechatronic products, the electric motor as a central component undoubtedly has a significant share in the overall cost structure. From the point of view of electric motor manufacturers and customers, there is a strong focus on cost optimization to get to cost optimized products.

Electric motor manufacturers and customer who focus on optimized electric motor development from the very beginning, increase their product competitiveness dramatically.

    Disclaimer – further notes and terms on the subject of electric motors for cars:

    The electric motor works exclusively with electricity and has no CO2 emissions during its operation. That is why the car with an electric motor is trendy and is being promoted by the government and industry. Apart from the question of the battery, which supplies the electric motor with the necessary energy, the electric motor itself plays an important role in vehicle development. Current, power and motor belong closely together as important building blocks. Special performance in this area is not available from an off-the-shelf motor.

    Not all motors are the same – and different requirements apply depending on the car and brand. Specialists are needed here. Because it is not only a battery that determines the performance of an electric car. Achieving higher efficiency is one of our goals. A motor for the car that is powered by electric current should be as profitable as possible for the customer. That is why we optimize electric motors with our expertise.

    General background information on electric motors, especially for electric cars:

    Electric motors for cars are a modern and environmentally friendly alternative to existing combustion engines. They convert electrical energy into mechanical energy that drives the car. Electric motors consist of two main parts: the rotor and the stator. The rotor is the moving part that rotates around an axis. The stator is the fixed part that surrounds the rotor and generates a magnetic field.

    There are various types of electric motors, which differ in terms of shape, torque, speed and type of current. An important difference is whether the motor is operated with alternating current or direct current. Alternating current is the current that comes from the socket and direct current is the current that comes from a battery. AC motors have the advantage that they are easier and cheaper to build, but they require a gearbox to regulate the speed. DC motors have the advantage that they can control the speed directly, but they need a commutator to change the direction of the current.

    A special type of electric motor is the synchronous motor, which is operated with alternating current and has a permanent magnet in the rotor. These motors have the advantage of being very efficient and powerful, but they require electronic control to adjust the frequency of the current. Synchronous motors are often used in electric cars because they enable a long range and good acceleration.
