Production Process

The slot commutator includes a plastic base and a slot commutating copper sheet. The top of the slot commutating copper sheet is provided with a welding wire step. The adjacent slot commutating copper sheets are insulated and isolated by mica sheets. The center has an upper cylindrical inner hole and a lower cylindrical inner hole coaxially arranged, and the hole diameter of the upper cylindrical inner hole is smaller than the hole diameter of the lower cylindrical inner hole,

Machine Features

1. Effectively improve mechanical strength and overspeed performance.

2. A copper bush is embedded in the upper cylindrical inner hole of the plastic base of the trough commutator,

3. The inner side of the reversing copper sheet is provided with an upper hook foot implanted in the plastic matrix at the upper position, and the top of the upper hook foot is bent toward the center of the commutator to form an inner hook.

4. The inner surface of the reversing copper sheet is provided with a lower hook foot implanted in the plastic base at the lower position, a reinforcing ring groove is formed between the lower hook foot and the inner surface of the groove-type reversing copper sheet, and a reinforcing ring is arranged in the reinforcing ring groove;

5. A dovetail structure is formed between the bottom of the upper hook and the top of the lower hook.
