New Energy Vehicle Core Technology-sensor Resolvers

Sensor resolvers are the key components of the new energy vehicle drive system, responsible for the transmission and conversion of electric energy.

How sensor resolvers work

The rise of new energy vehicles has brought revolutionary changes to the automobile drive system. As an important part of the new energy vehicle drive system, sensor resolvers play a key role in the transmission and conversion of electric energy.

The basic principle of sensor resolvers, sensor resolvers is a device that can transfer electrical energy in rotating motion, it is a combination of traditional transformers and rotating machinery, its basic principle can be summarized as follows.

The stator part of the sensor resolvers is usually composed of fixed coils called stator coils. These coils are in a fixed position and do not move with rotation.

A rotor part connected to a rotating device, usually consisting of a rotor coil. The rotor coil is the part that rotates around the axis of rotation, so it is also called the rotor.

Electromagnetic induction, when the stator coil through the current, will produce a magnetic field, this magnetic field will pass through the air or other magnetic materials, and then induce electromagnetic induction in the rotor coil. Because the rotor coil rotates, the electromagnetic induction changes accordingly.

Energy transfer and conversion. Through electromagnetic induction, energy is transferred from the stator coil to the rotor coil to realize energy conversion and transfer. This mode of energy transmission enables the sensor resolvers to output or input electrical energy during rotation.

In new energy vehicles, sensor resolvers are widely used in electric drive systems, mainly for energy transfer and matching between battery pack and motor. In electric vehicles, battery pack usually provides direct current energy, while motor needs alternating current energy to realize rotation.

The application of sensor resolvers enables the DC electric energy provided by the battery pack to be converted into AC electric energy suitable for the motor through the transformer, so as to drive the motor to achieve the power output of the vehicle.

This way of energy conversion and transmission makes electric vehicles efficient and flexible, and greatly improves the driving performance of electric vehicles.

The working flow of the rotating transformer system of new energy vehicles is roughly as follows: the battery pack provides direct current energy: The battery pack carried by the new energy vehicle stores electrical energy, which is the main source of energy for the vehicle.

The DC energy is converted into AC power by the inverter. In the sensor resolvers system, the inverter is responsible for converting the DC energy provided by the battery pack into AC power for further processing by the sensor resolvers.

Conversion of sensor resolvers: The AC electric energy converted by the inverter is adapted to the electric energy required by the motor through the conversion of sensor resolvers.

Finally, the electric motor receives the AC electrical energy from the sensor resolvers and converts it into mechanical energy, which drives the car.

As an important part of the electric drive system, sensor resolvers of new energy vehicles realize the efficient conversion of battery energy to the motor through the transmission and conversion of electric energy, providing stable power support for the power output of the vehicle.

Understanding the basic principle of sensor resolvers helps to better understand the working principle of new energy vehicles, and also has important guiding significance for the development and application of related technologies.

The future development trend of Sensor resolvers will be reflected in technological progress, cost reduction, application field expansion, integration and intelligent upgrading, environmental protection and sustainable development, and market expansion. Together, these trends will push the sensor resolvers industry to a higher level.
