複数の電動機組立体を備えた駆動装置
Document Type and Number:
Japanese Patent JP7132842
Kind Code:
B2
Abstract:
To provide a drive device including a plurality of electric motor assemblies capable of appropriately and automatically setting a frequency jump band.SOLUTION: A drive device includes a first electric motor assembly 1A and a second electric motor assembly 1B, and a frequency jump control unit 63. The first electric motor assembly 1A includes a first electric motor 2A, a first inverter 3A that supplies AC power to the first electric motor 2A, and a vibration sensor 60 fixed to the first inverter 3A, and the first inverter 3A is fixed to the first electric motor 2A. The second electric motor assembly 1B includes a second electric motor 2B and a second inverter 3B that supplies AC power to the second electric motor 2B, and the second inverter 3B is fixed to the second electric motor 2B. The frequency jump control unit 63 acquires an output value of the vibration sensor 60 while the first electric motor 2A and the second electric motor 2B are operating, and determines a frequency jump band on the basis of the acquired output value.SELECTED DRAWING: Figure 1
