Impregnation of electric Motors

The future of mobility is electric

The electrification of the powertrain is one of the biggest automotive trends worldwide. New mobility concepts and products are constantly emerging. Electric motors have been used in various automotive applications as chargers, ICE starters or system support (e.g. window regulators) for almost 100 years, but only in recent years as drive motors.

Electric-car motors must be as compact and lightweight as possible. They are also subject to strict efficiency and energy density requirements. In the automotive sector, all quality-relevant materials, process parameters and test results must be traceable to each motor. bdtronic offers a sophisticated impregnation technology for the secondary insulation of electric motor stators and rotors.

bdtronic offers numerous technologies for tomorrow's mobility, including the impregnation of electric motors.

Electric motor

An electric motor is a device that converts electricity into motion to produce a rotational force called torque. In general, there are two types of electric motors used in automotive applications: the permanent magnet motor and the induction motor. For asynchronous motors, bdtronic offers its experience in the impregnation of rotors using the trickle or roll dipping process.

The stator of any electric motor is insulated to provide better mechanical strength and overall improved performance. The impregnation is also called secondary insulation because it reinforces the copper enamel, which is defined as the first insulation.

bdtronic offers a highly developed impregnation technology for the secondary insulation of stators and rotors of electric motors.

Electric drives

Battery Electric Vehicles (BEV), or pure electric vehicles, is a type of electric vehicle (EV) that exclusively uses energy stored in rechargeable battery packs. BEVs use electric motors and motor controllers instead of internal combustion engines (ICEs) for propulsion.

A hybrid electric vehicle (HEV) combines a conventional powertrain, usually an internal combustion engine, with an electric engine. Full hybrid, sometimes also called a strong hybrid, is a vehicle that can run only on a combustion engine, only on an electric motor, or a combination of both.

Mild hybrid, is a vehicle that cannot be driven solely on its electric motor, because the electric motor does not have enough power to propel the vehicle on its own, but will boost the vehicle during the start moving.

A Plugin Hybrid Electric Vehicle (PHEV) also known as a plug-in hybrid, is a hybrid electric vehicle with rechargeable powerful batteries with a OBC (On Board Charger system), an electric motor and an internal combustion engine.
