Overview

The single coil resolver (also known as a reluctance resolver) is an inductive rotary position sensor and is used to determine the rotor position in electric motors.  It works like a transformer, with a primary coil and two secondary coils, whereby the amplitude of the secondary voltages is modulated by the rotor to get sine and cosine signals. In electric vehicles, the rotor position sensor is one of the most important technical components for precise and effective control of the motor and thus for avoiding efficiency losses, vibration, and noise.

Key Features

  • Temperature range: -40°C to +150°C
  • Accuracy: ±1° electrical
  • Speed range: Up to 20,000 rpm
  • High number of different variants available
  • Combined temperature sensor option
  • Oil or glycol compatibility
  • ASIL D on system level
  • Customized cable assembly and connector interface
  • High accuracy performance with eccentricity (static / dynamic)
  • Robustness against external fields

Applications

  • eMotors for automotive, industrial and commercial transportation

Fault Tolerant

Against Eccentricity and External Fields through Patented Windings Schemes

Our single coil resolver provides patented solutions designed to improve the immunity against external magnetic fields that can come from motor windings and/or permanent magnets on the shaft.

 

Also, the unique rotor geometry provides improved accuracy in combination with eccentricity.

Vertical Integrated Solutions

As a unique provider, we deliver rotor position sensors with access to comprehensive vertical integration, including connectors, cable assemblies, and additional sensors like NTC temperature sensors. This approach helps streamline system compatibility and efficiency.
