01 / DEFINE THE DRIVEN MACHINE
A mill's torque path is a different purchase from a molding servo
TDMK: design the mill interface before the nameplate
The manufacturer's TDMK/TM page identifies a large AC synchronous family for ball, rod and coal mills. It specifies a welded-steel construction and either open natural ventilation or a fully enclosed ducted-air option. Its coupling arrangement is described as transmitting torque without imposing axial or radial loads on the motor; a pneumatic clutch is suggested for heavy starting. Sliding bearings can use oil-ring or combined external-oil lubrication depending on the design. These are configuration choices, not one universal motor specification.
Confirm before ordering Send mill type, loaded starting torque and inertia, operating speed and start frequency, site voltage/frequency, coupling and shaft drawing, ambient/dust conditions, cooling-air plan and available lubrication system. Ask for the selected motor's torque-speed/start study, coupling load limits, bearing/lube drawing and routine-test schedule.

ST200–260: treat the motor, drive and hydraulic pump as a system
Jianghuai's catalogue names an ST200–260 injection-molding servo family under permanent-magnet servo products. The public detail page currently provides the family name but no usable rating table, winding data or torque curve. Frame size in the family name is not evidence that a specific motor has the required continuous torque, overload duty or encoder interface. The supplier's wider catalogue also lists converters, but compatibility must be established for the actual motor-drive-pump combination.
Confirm before ordering Provide machine clamp/injection cycle, pump displacement and pressure-flow curve, required speed and torque over the full cycle, drive supply/DC bus, feedback interface, shaft/flange and cooling envelope. Request the exact ST code, continuous and peak torque curves, matched-drive settings, pump-coupling drawing and an application-level test result.

02 / PUT THE CLAIMS IN SCOPE
A real motor manufacturer, but evidence must match the order
The same Lu'an legal entity appears in public records
The Jin'an District government profile identifies Lu'an Jianghuai Motor Co., Ltd. and lists high-voltage, efficient, variable-frequency, permanent-magnet and special-purpose motor families, including TDMK mill drives. It also describes a motor test center. Those company-wide capabilities support supplier identity and a plausible test route; they do not establish the performance or acceptance criteria for the two exact catalogue entries on this page.
Standard drafting is a capability signal, not a certificate
The national standards information platform names the legal entity among drafting organizations for the GB/T 755-2025 rotating-machine rating and performance revision. This is participation in a general standard, not a product approval, mining permit or third-party validation of a quoted ST or TDMK motor. Ask for the test report and applicable standard edition on the exact order.
Keep unrelated green-product recognition separate
A Lu'an municipal announcement identifies a Jianghuai YE4 high-efficiency three-phase motor series among 2020 green products. That historic recognition concerns YE4, not the TDMK mill motor or ST200–260 servo. It should not be copied onto their quotations or product badges.
03 / REQUEST A BUILDABLE ANSWER
Ask for one named configuration and its acceptance evidence
For a mill retrofit
Identify existing mill and gearbox/coupling, shaft centre height, foundation, line supply, control/start method, inertia and loaded duty. Have the supplier state the exact TDMK build, ventilation and bearing-lubrication arrangement, shaft-current protection and whether an external oil station or starting clutch is required. Request a dimensional drawing and a motor test plan tied to that build.
For an injection-molding drive
State hydraulic pump and machine cycle, pressure/flow points, supply and inverter, feedback protocol, mount, enclosure and cooling. Require a specific ST designation plus its torque-speed and thermal data, matching drive configuration and a bench or machine acceptance criterion. Do not compare a peak-torque headline with another supplier's continuous-duty rating.
