我院FV－KXO－850X线诊断机上下床运动电动机绕组匝间短路，该电动机是三组绕组（见图1），属专业特种电机，无法购买到。重新按原型号下线，线槽图1图2容线量不够。将电动机改造成两绕组四抽头正反转型式（见图2），同时电路也需要改动（见图3，图4），将GT1中的23，24短接。? The FV-KXO-850X diagnostic machine in our hospital has a short-circuit between windings of the motor windings on the bed. The motor is a three-part winding (see Figure 1). It is a professional special motor and cannot be purchased. Re-invented the original model, wire slot Figure 1 Figure 2 The amount of capacity is not enough. Transform the motor into a two-winding, four-tap forward-reversing pattern (see Figure 2), and the circuit also needs to be modified (see Figure 3, Figure 4). Short-circuit the 23, 24 in GT1. ?
