Title:
同期リラクタンスモータの回転子及び同期リラクタンスモータ回転子の二次導体バー形成方法
Document Type and Number:
Japanese Patent JP7177624
Kind Code:
B2
Abstract:
To easily form a conductor bar for a synchronous reluctance motor rotor.SOLUTION: This synchronous reluctance motor rotor comprises: a first electromagnetic steel plate that is an electromagnetic steel plate constituting the iron core of the synchronous reluctance motor rotor and that includes a plurality of flux barrier slots and a conductor slot provided so as to form a conductor bar; and a second electromagnetic steel plate that is an electromagnetic steel plate constituting the iron core and that includes only the conductor slot. The second electromagnetic steel plate is disposed in each of uppermost and lowermost layers, a plurality of first electromagnetic steel plates are laminated between the uppermost and lowermost layers, the conductor bar is formed in the conductor slot, and a short-circuit ring is formed on each of the upper and lower end sides of the conductor bar.SELECTED DRAWING: Figure 3
