structure of permanent magnet dc motor





These DC motors have constant torque characteristics over the entire speed range. Ruggedness, dependability, and extended warranty make our products worry-free and the best in the industry. Each motor is run up to 4four hours at our inspection facility to ensure the best performance and the lowest noise level.

All of the DC motors have permanently lubricated ball bearings, and easy access brush/spring assembly for trouble-free maintenance. We offer NEMA frame DC SP motors in both TEFC (totally enclosed fan-cooled), and TENV (totally enclosed non-vent) enclosures for the complete horsepower range, while all other motor companies offer only TENV enclosure for 1/2HP and under. All of the motors have NEMA C flange face and removable casting foot for mounting versatility.



These DC motors have the following major advantages:
1.Highest quality oriented magnets for increased motor efficiency;
2.Armature connections fused to commutator for reliability and low resistance;
3.Removable casting base for mounting versatility and improved rigidity;
4.Dynamic balanced armature for smooth operation; Fan cooling for no temperature increase;
5.Double seal ball bearings with permanent grease filling for long life;
Long life brushes;
6.Powder coating exterior for much better looks and scratch proof;
7.Unique clamp protections prevent lead wires from pulling off;
8.Reinforced C-face flange and all die casting construction is the best in the industry
