DC motors are used in a variety of fields, and in recent years, more accurate motor speed-measurement has become a key factor for the use of electric vehicles. In this case, OM-1200 electromagnetic-induction type detector is used. It is installed in parallel with rotation axis of DC motor to detect leakage flux from DC motor. Then frequency-analysis by FFT calculation process is performed with FT-7200 advanced handy tachometer, and the rotation speed is displayed. <\/p>\n<p class=\"mt50\">FT-7200 is equipped with analog output and analog output for monitoring as standard. The analog output can be used to record changes in rotational speed with a pen recorder, etc., while the analog output for monitoring can be used as a waveform check signal.\n\t<\/p>\n<\/p><\/div>\n<\/section>\n<p>\t<img decoding=\"async\" class=\"mb50\" src=\"https:\/\/www.n-denkei.com\/media\/wp-content\/uploads\/sites\/13\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2023-03-28-9.19.11.png\" style=\"margin-top: 50px; margin-bottom: 20px;\"><\/p>\n<p class=\"mt50 mb50\" style=\"margin: 0px 0px 80px 0px;\">Illustration creation cooperation : ONOSOKKI  ,   HIOKI CORPORATlON<\/p>\n<\/div>\n<\/section>\n<!--\u30b3\u30f3\u30c6\u30f3\u30c4\uff13\u3053\u3053\u304b\u3089-->\n<section class=\"post-content\">\n<h2>Product Details<\/h2>\n<hr class=\"orange\">\n<div class=\"flex-container mt100\">\n<div class=\"flex-items\">\n<div class=\"item-img\"><img decoding=\"async\" src=\"https:\/\/www.n-denkei.com\/media\/wp-content\/uploads\/sites\/13\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2023-03-28-9.33.12.png\"><\/div>\n<div class=\"item\">\n<p>Advanced Handy Tachometer FT-7200<\/p>\n<p><a class=\"btn-find-out-more\" href=\"https:\/\/www.n-denkei.com\/vietnam\/items\/product\/onosokki-advanced-handy-tachometer-ft-7200\/\n\">find out more<i class=\"fa fa-angle-right\"><\/i><\/a><\/div>\n<\/div>\n<div class=\"flex-items\">\n<div class=\"item-img\"><img decoding=\"async\" src=\"https:\/\/www.n-denkei.com\/singapore\/wp-content\/uploads\/sites\/3\/2022\/05\/LR8450.png\"><\/div>\n<div class=\"item\">\n<p>Memory HiLogger LR8450<\/p>\n<p><a class=\"btn-find-out-more\" href=\"https:\/\/www.n-denkei.com\/vietnam\/items\/product\/hioki-lr8450-thiet-bi-ghi-du-lieu\/\n\">find out more<i class=\"fa fa-angle-right\"><\/i><\/a><\/div>\n<\/div>\n<p><!-- \n\n<div class=\"flex-items\">\n\n\n<div class=\"item-img\"><img decoding=\"async\" src=\"http:\/\/dev.n-denkei.com\/indonesia\/wp-content\/uploads\/sites\/2\/2023\/01\/anechoic_chamber_s.jpg\"><\/div>\n\n\n\n\n<div class=\"item\">\n\n<p>Anechoic chamber<\/p>\n\n<a class=\"btn-find-out-more\" href=\"\/indonesia\/topics\/2967\/\">find out more<i class=\"fa fa-angle-right\"><\/i><\/a><\/div>\n\n -->\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>\u3000\u3000 Measuring the rotational speed of DC motors in EV vehicles (FFT arithmetic process) Summary Description This instrument measures the rotational velocity of DC motor.
