DRIVING METHOD AND DRIVING DEVICE OF MOTOR AND BRAKE
To prevent damage to an emergency power supply when a motor and a brake are driven by an emergency power supply while suppressing costs.SOLUTION: In a driving method of a motor 40 and a brake 42 by using a commercial power supply 32 in normal times and an emergency power supply 34 in a power failure as a driving power supply 30, the driving power supply 30 and the motor 40 are connected through a first switch 12, and the driving power supply 30 and the brake 42 are connected through a second switch 14. When the driving power supply 30 is the emergency power supply 34, the first switch 12 and the second switch 14 are separately controlled to raise an object by driving the motor 40 with the brake 42 released, and to lower the object by driving the motor 40 with the brake 42 actuated. As a result, since the motor 40 does not enter a power regeneration state, damage to the emergency power supply 34 can be prevented while suppressing costs without requiring a braking resistor or the like.SELECTED DRAWING: Figure 1
【課題】コストを抑制しながら、非常電源によるモータ及びブレーキの駆動時に、非常電源に対する損傷を防止する。【解決手段】通常時は商用電源３２を、停電時は非常電源３４を駆動電源３０として、モータ４０及びブレーキ４２を駆動し、駆動電源３０とモータ４０との間を第１の開閉器１２を介して接続すると共に、駆動電源３０とブレーキ４２との間を第２の開閉器１４を介して接続し、駆動電源３０が非常電源３４のとき、第１の開閉器１２と第２の開閉器１４とを別個に制御して、ブレーキ４２を開放した状態でモータ４０を駆動することで物体を上昇させ、ブレーキ４２を作動させた状態でモータ４０を駆動することで物体を下降させる。これにより、モータ４０が電力回生状態になることはないため、制動抵抗器などを要することなくコストを抑制しながら、非常電源３４に対する損傷を防止することができる。【選択図】図１
