By monitoring the distribution of magnetic field strength in the motor, RVmagnetic’s Mi­croWire is able to collect data from the motor in contactless. Placing the passive part of our technology – the MicroWire – on the inner part of motor chassis right in the middle between the coils where magnetic fields are negated allows us to record the changes of temperature, velocity of the motor, the output in the real time and up to 10.000 times per second. It needs no power wiring and is indeed the winner in space saving category often in need in electric engines. The power-wired part is the sensing head (reading coil) that needs to placed in the distance of 10cm from the MicroWire.

Technology also allows to determine the exact position of the rotor and detecting the faults in an instance. On top of it – though being the magnetic sensor – measurements are not affected by magnetic field of the electromotor.

Unlock the full potential of your electric engine and prolong its operating life with RVmagnetics MicroWire.

Features

1. Dimensions
Allow introduction of microwires inside various materials without affecting their properties; including implanting the MicroWire to human tissue.

2. Lifespan
Lifespan of the sensor itself is longer than 1000+ yrs.

3. Passive sensor
Sensor requires no power source (only sensing device is low-powered).

4. Low power consumption (Sensing system/device)
Sensing system/device is powered in Microampere (µA).

Need for smart electric motor

  • current solutions are cost intensive
  • current solution is suitable for use in laboratory, not for mass production of electric motors
  • limited potential in maximizing efficiency because of Curie temperature limit
  • no global opportunity to detect temperature from inside of the electric motor
  • power consumption rate is too high
  • predictive maintenance has not been achieved

MicroWire Sensing possibilities

  • Temperature
  • Vibration
  • Tensile stress
  • Rotation speed
  • Position of rotor vs. stator

Significant benefits

  • measures temperature in the real time
  • increases efficiency and effectiveness by maximizing the potential of motor physical limits (can also later lead to motor / chassis size reduction)
  • decreases power consumption
  • measures temperature, position, RPM with one communication interface
  • detects faults inside of the motor – and helps optimizing predictive maintenance
  • needs no change the industrial design
  • simple plug & play solution
  • prevents motor burnouts
  • decreases power consumption
  • optimizes reverse logistics
  • environment friendly
