  1. 1. An amplitude modulated laser rangefinder : electronic circuit design and implementation

    University essay from Uppsala universitet/Signaler och system

    Author : Fazel Naser; Stefan Morin; [2022]
    Keywords : Amplitude modulation; Phase shift; Laser rangefinder; Drive electronics; PCB; Colpitts crystal oscillator; Transimpedance amplifier;

    Abstract : This report describes the design and implementation of a prototype for an amplitude modulated laser rangefinder, which is made on a PCB consisting of a laser module emitting light, a photodiode receiving the light reflected from the target, and other components. The design is made for the different power levels, generation of the modulation output and the reception of the signal. READ MORE

  2. 2. Bearing current and shaft voltage measurement in electrical motors

    University essay from Högskolan Väst/Avdelningen för data-, elektro- och lantmäteriteknik

    Author : Edo Kolic; [2017]
    Keywords : Modulated drive; electrical motors; production;

    Abstract : Due to the fast-rising voltage pulses of pulse width modulated drives, the generated shaft voltage of electrical motors causes electrical discharge currents in bearings. These discharges can cause bearing failure leading to costly maintenance and unexpected production stops. READ MORE

  3. 3. Electromagnetic Noise from Permanent Magnet Motors

    University essay from KTH/Farkost och flyg

    Author : Sajan Varghese; [2013]
    Keywords : ;

    Abstract : With today’s increase in rail traffic the impact of noise on the people near railway lines is increasing. To control this problem European Union regulations, including TSI (Technical Specifications for Interoperability) Noise, has come into force by implementing many strict norms on new railway vehicles put on the market.
