Extranet Antriebsmotor Test Drive motor test PROCESS TECHNOLOGIES Classification Internal use only Page 2/2 Created 18.01.2011RL Modified Language German / English You can test all the LEISTER DC-Motors while using a rectifier We recommend to use a kind of “variable ratio transformer” to raise the voltage step by step This allows you to check all the time the actual current consumption Means you could react if there is something wrong (you don’t have this chance if you connect directly the standard voltage) On a defective motor you would see a distinctive raising current consumption while you raise the voltage on the transformer In such a case you can switch off the tool, before you overheat the rectifier because of a too high current consumption ~ Alternating voltage VAC ~ Order number rectifier 101.851 (Without the clips and cables)! ~ ~ + Example of a variable ratio transformer (type „Tufvasson“) Direct voltage (VDC) © Leister 2011 01.03.2011 Seite von
