PROBLEM TO BE SOLVED: To provide an electromagnetic suspension apparatus capable of improving safety and reliability.SOLUTION: Relays 27, 28 are provided on 2-phase power lines 6A, 6B of 3-phase power lines 6A, 6B, 6C connecting coils 15A, 15B, 15C of a linear electromagnetic actuator 2 with output parts 3A, 3B, 3C of an inverter 3. The relays 27, 28 include: a control contact 29 for allowing current to flow between the coils 15A, 15B and the output parts 3A, 3B of the inverter 3; and a short-circuit contact 30 for performing short-circuit on the coils 15A, 15B, 15C to allow current to flow between the coils 15A, 15B, 15C. The relays 27, 28 have a configuration including: a fixed contact 34 composed of the control contact 29 and short-circuit contact 30; and a movable contact 31 that is provided between the control contact 29 and short-circuit contact 30, becomes in contact with the control contact 29 by being guided by a magnetic material 40 during energization to an operation coil 38, and becomes in contact with the short-circuit contact 30 by spring force of a spring 37 during a non-energization period.

    【課題】安全性、信頼性を向上することができる電磁式サスペンション装置を提供する。【解決手段】リニア電磁式アクチュエータ2のコイル15A,15B,15Cとインバータ3の出力部3A,3B,3Cとを接続する3相の動力線6A,6B,6Cのうち2相の動力線6A,6Bにリレー27,28を設ける。リレー27,28は、コイル15A,15Bとインバータ3の出力部3A,3Bとの間で電流を流す制御接点29と、コイル15A,15B,15Cを短絡しコイル15A,15B,15C間で電流を流す短絡接点30を有する。この場合、各リレー27,28は、固定接点34となる制御接点29と短絡接点30の間に可動接点31を設け、該可動接点31は、操作コイル38への通電時に磁性体40に導かれることにより制御接点29と接触し、非通電時にばね37のばね力により短絡接点30と接触する構成とする。【選択図】図1
