Seimec Two-speed Three Phase Motors – Series HPDSEIMEC's two-speed three phase square type motors Series HPD enables users to vary the motor speed simply and cheaply to best meet the needs of its application while achieving energy savings.
The pole switching motor series, featuring Dahlander connection and a single winding, is available with a 1:2 speed ratio.
Compared to the IEC construction, the frame shape built in a light aluminium alloy expands the motor's work envelope and machining precision of tools, if used. The extended bearings and output shaft provide for rigidity and reliability.
The IM B34 construction shape is suitable for both foot and flange mounting.
Flanges can also be used for mounting protections or casings. The terminal box can be located on either side of the motor in frontal position as well as next to the fan cover.
