To provide an electric braking device which suppresses deterioration of braking force even if an abnormality occurs in control systems of three-phase windings of a motor.SOLUTION: Wheel brake equipment 4 is provided in each of right and left wheels. The wheel brake equipment 4 includes: a motor 7 which has a set of three-phase windings 11 and 12; first and second inverters 21 and 22 which drive the motor 7; and a control device 40 which controls the inverters. When an abnormality occurs in a control system of the one three-phase winding 11 (or 12), the control device 40 controls the operations of the first and second inverters 21 and 22, makes supply current to the three-phase winding 11 (or 12) in which the abnormality occurs to zero, and increases supply current to the other three-phase winding 12 (or 11) more than that in a state before the occurrence of the abnormality by setting a preset increase upper limit current value as an upper limit.SELECTED DRAWING: Figure 4
【課題】モータの3相巻線の制御系統に異常が生じても制動力の低下を抑制した電動制動装置を提供する。【解決手段】左右の車輪に車輪制動器4が設けられ、車輪制動器4は1組の3相巻線11、12を有するモータ7を備えるとともに、モータ7を駆動する第1、第2のインバータ21、22と、これを制御する制御装置40と含み、制御装置40は、いずれか一方の3相巻線11(又は12)の制御系統に異常が発生した場合には、第1、第2のインバータ21、22の動作を制御して、その異常発生した3相巻線11(又は12)への供給電流を零にし、他方の3相巻線12(又は11)への供給電流を予め設定した増加上限電流値を上限として異常発生以前の状態よりも増加させる。【選択図】図4
