Page 6: Purpose
OPERATING MANUAL for BRAKE UNITS 6 of 19 JB10/... JB16/... JB26/... JB40/... JB52/... 01.96/00/Scho (Installation set) PURPOSE JB brake units are intended to brake manufacturers' unbalanced motors or three-phase motors used in conjunction with vibrating machineries. In conjunction with an existing motor control system, or one to be installed separately, the JB brake unit is used to shorten the coasting period of the machine after it is switched off. -
