Shift Motor with Mode Sensor - Description

DESCRIPTION




Figure 1 - MP1522 TRANSFER CASE





The shift motor (3) is an electromechanical device consisting of a DC permanent magnet motor, a gear train and an analog position sensor. The shift motors' overall function is to move and lock a gear that moves the range fork found in the transfer case. This allows the transfer case to be shifted electrically to multiple operating positions (4WD LOW, 4WD LOCK and 2WD). The operating current of the shift motor under stall conditions is 30 amps maximum at 72° F with 13.5 volts, at the motor leads.
