  1. 36. Test rig for study of pre-synchronization in gearboxes

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Johan Holmberg; Viktor Lindholm; [2015]
    Keywords : ;

    Abstract : Detta arbete är en fortsättning på ett tidigare masterarbete inom maskinkonstruktion. I det tidigare arbetet designades och tillverkades en testrigg för att mäta oljefilmsbortträngning mellan två metalliska ytor i en växellåda. READ MORE

  3. 37. Implementing and Analyzing Single Edge Nibble Transmission (SENT) Protocol for Automotive Applications

    University essay from Högskolan i Jönköping/JTH, Data- och elektroteknik

    Author : Naseem Ullah; [2014]
    Keywords : SENT Protocol; CAN; PWM; FPGA; DE2 Board; Quartus-II; Nios-II;

    Abstract : With advancement in automotive systems, it is not just the combination of mechanical devices like in old days. Almost all the systems of today's modern car are controlled electronically by a number of ECUs (Electronics Control Unit) with the combination of sensor modules. READ MORE

  5. 39. Perceptual Characterization of a Tactile Display for Live Electronic Music Performance : Designing a Vibrotactile Notification Tool for the CIRMMT Live Electronics Framework (CLEF)

    University essay from KTH/Medieteknik och interaktionsdesign, MID

    Author : Emma Frid; [2014]
    Keywords : Haptics; Live-Electronics; Vibrotactile Feedback;

    Abstract : This study was conducted to assess physical and perceptual properties of a tactile display for a vibrotactile notification system within the CIRMMT Live Electronics Framework (CLEF), a Max-based modular environment for composition and performance of live electronic music. The tactile display was composed of two rotating eccentric mass actuators driven by a PWM signal generated from an Arduino microcontroller. READ MORE

  6. 40. Design and implementation of a servo system by Sensor Field Oriented Control of a BLDC motor

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Per Eriksson; [2014]
    Keywords : Field oriented control; Vector Control; BLDC; Servo system; Regulator; Synchronous motor; PWM; SVPWM;

    Abstract : A servo system intended to steer antennas on board ships is designed, built and tested. It uses a Brushless Direct Current (BLDC) motor with an encoder to keep track of its position, and Field Oriented Control (FOC) implemented on Toshibas microprocessor TMPM373 in order to control the current flowing to the motor.
