Performances of our electric DC motors
1. The rated voltage of our electric direct current motor falls into 7 levels, that is, 220V, 330V, 440V, 550V, 660V, 750V, and 850V. Other voltage levels are also possible.
2. Our direct current electric motor adopts separate excitation. Its excitation winding has four lead terminals which are divided into two groups. The excitation voltage is 220V when the two groups are in series connection, and 110V in parallel connection.
Forced excitation is also allowable, but the forced excitation voltage should be no more than 500V. During forced excitation, the transient excitation current can exceed the rated excitation current until the excitation current gets stabilized.
3. Short period overload capacity of our DC motors.
(1) Overload capacity of industrial DC motors within 1min.
