Motors control VV series - KELVIN - #1

Text version of the page

Control: Kelvin encoder, type 502 with 2 carrier channels, very accessible and easily cleaning even in dusty conditions. An electronic circuit receives the impulses and converts them into currents which are comparable to those of the reference, selected by an external potentiometer which determines the speed variation. TECHNICAL CHARACTERISTICS ð¯ Speed ratio up to 20:1. ð¯ Power supply 230 V. 50 Hz. (Other voltages and frequencies available). ð¯ Available current up to 2 A. ð¯ For motors with a Ø4-Ø6-Ø8-Ø10 shaft. KELVIN ENCODER, type 502. ð¯ 2 channels, 50 pulses per turn. ð¯ The 2 channels have an external outlet, an open collector (O.C.). ð¯ Resolution, 1/200 per turn with a frequency of 50 pulses per turn. ð¯ 4 fixation points with spacers for M3 screws. ð¯ Net weight 0.170 Kg. ð¯ The set includes: ð¯Motor K90.M4-RF-VV, cooling fan, with a coupled 502 encoder. Control circuit VV + potentiometer 10 K. VV... Speed changer for KELVIN SINGLE-PHASE motors induction, series G... and 4 poles K90.M4 VV... series Bidirectional SPEED CONTROL FOR SINGLE-PHASE A.C.
