DC Motors: High Voltage DC Motors (HVDC)

HVDC motors can be connected to mains supply voltage level 120 Vac or 230 Vac.
JE has special expertise to design motor components accordingly, especially the commutator assembly.

A rectifier is needed to convert AC into DC.
It is located inside the motor (if there is space available) or outside.
A changeover switch enables bidirectional operation.

HVDC can replace Universal motors in some applications.

Advantage is a reduction of copper material (use of permanent magnets instead of stator field winding) and less weight.
