Design is a problem, and the most of numbers of poles of submersible motor are all 2 in addition, and number of poles is few, and permanent magnet magnetic Circuit Design difficulty is big, magnetic field road
Line and loss are big, how to rationally design magnetic circuit, and carry out the design for completely cutting off magnetic circuit, select the magnet dosage of economy, make magnet
Service life and the magnetic in water during use, which weaken, must also take necessary safeguard procedures；How to overcome after the completion of design latent
The elongated shortcoming of hydroelectric machine, it is all technical barrier to realize process operability.It is simultaneously the control cabinet matched secondary of reduction user
Equipment investment, the design of electrical motor structure operated using the asynchronous starting permanent-magnet synchronous with squirrel-cage bar can preferably solve problem.
