Patent
Temperature sensing by magnetic field changes
TL;DR: In this paper, the temperature of a section of a first part of a rotatable energy converter is determined by a permanent magnet that is thermally coupled to the section of the first part, and a sensor arranged on the second part for determining the magnetic field of the permanent magnet.

Patent
Magnetic temperature sensor
TL;DR: In this paper, a thin layer of a material of sufficiently high magnetic permeability and Curie temperature is bonded to the surface to be monitored and a magnetic field is induced in the layer.
Patent
Apparatus for measuring at least one state variable of a brushless direct-current motor
TL;DR: An apparatus for measuring at least one state variable of a brushless direct-current motor includes 2 * n pole segments, wherein n = 1, 2, 3, etc. as mentioned in this paper.
Patent
Electronically commuted motor
Gerald Hogg,Arno Karwath +1 more
TL;DR: In this paper, a method for operating an electronically commuted motor with a rotor and a stator was proposed. But the rotor was not provided with a regulator, whereas the regulator was provided with the first value as actual value and the second value as set value.
Patent
Permanent magnet temperature sensor, permanent magnet motor, and drive system thereof
Takasuke Kaneda,敬右 金田 +1 more
TL;DR: In this paper, the authors proposed a permanent magnet temperature sensor which can estimate the temperature of the permanent magnet in a rotor, and a drive system which can suitably drive such a magnet motor in response to the estimated temperature.
Patent
Motor protection device
TL;DR: In this article, the rotary speed of a motor is detected by a sensor magnet 2 and a Hall IC 3, and also a temperature near a stator coil winding 6 was detected by one temperature detection means 4 and is fed back to an inverter 7, conduction from the inverter to the motor 1 is stopped when a state where a rotary speeds is equal to or less than a specific rotaryspeed continues at least for a specific amount of time, and the power feeding is stopped also when the temperature detection mean 4 detects a given temperature or higher.
