TDMK (TM) series large AC three-phase synchronous motor for mining mills

product overview

1. This series of motors (including TDMK series brushed synchronous motors and TMW series brushless synchronous motors) are widely used in industries such as mining and cement due to their high starting torque. Mainly used to drive mechanical equipment with low rotational speed and high power, mainly driving grid ball mills, rod mills, coal mills, etc.

2. This series of synchronous motors complies with GB755 "Rating and Performance of Rotating Electrical Machines" and JB/T1473 "Technical Conditions for Large AC Three phase Synchronous Motors for Mining Grinding Machines".

3. This series of motors comes in various voltage levels such as 380V, 3300V, 6000V, 6300V, 6600V, 10000V, 11000V, etc. Electric motors can be started directly at full voltage, or they can be started with reduced voltage.

Structural characteristics

1. The shell protection level of this series of synchronous motors is various types such as IP00, IP20, IP23, IP44, IP54, etc. The cooling method can be made into various forms such as open natural ventilation IC01, duct ventilation IC37, etc.

2. This series of motors consists of three main parts: stator, rotor, and base plate.

Stator: The machine base is welded from steel plates. The stator core is made of 0.5mm thick low loss silicon steel sheets stacked together, and the core segments are separated by radial ventilation ducts. The stator coil adopts F-level insulation (temperature rise is assessed according to B-level);

Rotor: The magnetic pole core is made of 1.5mm thick steel plates stacked together, and the magnetic pole coil is insulated with F-level insulation (temperature rise is assessed according to B-level); When the user uses a pneumatic clutch, the shaft can be drilled according to the user's requirements. The TDMK (TM) series brushed synchronous motor has a steel slip ring installed on the shaft. The TMW series brushless synchronous motor is equipped with an AC excitation machine and a rotating rectifier disk on the shaft, and is also equipped with a secondary excitation cabinet;

Bottom plate: It is a steel structure, welded with steel plates of 20-30mm or more.
