1 / 5
TDMK series of large AC three-phase synchronous motors for mining mills are the core driving equipment for mining, cement and other industries. This series of motors (including TDMK series brush synchronous motors and TMW series brushless synchronous motors) are widely used due to their large starting torque. It is primarily used to drive mechanical equipment with lower speeds and higher power, such as grate ball mills, rod mills, and coal mills.
| Part | Inspection Item |
|---|---|
| Coil | Raw material tests, winding process inspection, dimension checks |
| Iron Core | Silicon steel material reports, lamination burrs, dimensional check |
| Frame | Cold welding certificate, finish machining inspection |
| Rotor | Core lamination, bar welding, dynamic balance correction |
| Shaft | Raw material annealing check, finish machining check |
| Stator | Core compactness, iron consumption check, winding insertion check |
Each motor undergoes rigorous testing before leaving the factory to ensure performance.
| Routine Test Items | Type Test Items |
|---|---|
| Insulation resistance to ground | Full load current & power factor |
| Withstand voltage test | Stator/Rotor winding loss |
| No-load current & power | Mechanical & Iron loss |
| Locked rotor current/torque | Temperature rise (Stator/Bearing) |
| Vibration & Noise levels | Efficiency & Overload test |
