Motor Identification via Stator Nameplate

Accurate component engineering for Shenyang Electric Machine / Tellhow Shenyang Motor machinery requires the serial number and full designation from the stator stamped plate.

When submitting an inquiry, record the exact series code (such as YE3 250M-6, YKK 450-4, or TDMK 800-36/2600), rated power output in kilowatts, line voltage, operating frequency, and full-load synchronous rotation speed.

For synchronous mill drives and flameproof versions, specify the exciter setup and hazardous zone environment ratings.

Providing a sharp photograph of the metal stamped plate enables engineers to confirm the exact factory lamination revision, winding configuration, and drive shaft connection dimensions.

Bearing Selection and Lubrication Regimes

Industrial drives by Shenyang Electric Machine / Tellhow Shenyang Motor feature rolling element or hydrodynamic sleeve bearings determined by torque and radial forces. Standard YE3 and medium YKK units utilize heavy-duty ball and cylindrical roller bearings with internal clearance C3.

High-capacity horizontal drives and vertical YL units incorporate specialized fluid-film thrust assemblies with pressurized oil recirculation.

To sustain smooth operation, maintenance personnel should apply recommended lithium complex or synthetic lubricants, follow specified regreasing intervals via factory grease fittings, and purge exhausted lubricant from relief passages periodically.

Slip Ring and Brush Gear Maintenance

Synchronous mill motors TDMK and wound rotor induction machines YR feature collector rings and brush gear assemblies. Routine inspections verify uniform pressure from constant-force brush holder springs across all carbon brushes.

Brush wear must remain within the limit indicator marked on the brush body, while collector ring tracks must maintain a smooth surface free of circumferential grooving, pitting, or electrical sparking marks.

When replacing brushes, select OEM grade materials matching electrical resistivity ratings, and bed new brushes to the ring radius using fine abrasive bedding cloth prior to energizing.

Thermal Monitoring and Stator RTD Detectors

High-voltage machines from Shenyang Electric Machine / Tellhow Shenyang Motor incorporate platinum resistance temperature detectors PT100. Sensors are embedded directly within the stator slots between winding coil sides, as well as positioned inside front and rear bearing housing jackets.

Continuous temperature monitoring protects Class F insulation systems (thermal limit 155 degrees Celsius) from overheating and prevents bearing damage caused by heavy operational loading.

Detector output wiring terminates inside an auxiliary terminal box for direct integration with plant industrial automation networks.

VPI Insulation and High-Potential Testing

Stator windings in Shenyang Electric Machine / Tellhow Shenyang Motor drives are constructed from formed rectangular copper conductors insulated with mica tapes and impregnated using solvent-free Vacuum Pressure Impregnation (VPI).

Routine maintenance protocols include insulation resistance evaluation with a 2500 V megohmmeter relative to ground and between phases. The polarization index at room temperature should exceed 1.3, confirming absence of moisture ingress or particulate contamination on winding overhangs.

Major overhauls include controlled alternating-current high-potential dielectric integrity testing.

Vibration Analysis and Coupling Alignment

Long-term operational reliability of heavy electric drives paired with mills, pumps, and blowers depends on precise coupling alignment and foundation structural rigidity.

For Shenyang Electric Machine / Tellhow Shenyang Motor units, maximum radial and angular shaft runout should remain within 0.04 mm during optical laser alignment. Stator support feet must rest on precision metal shims to prevent soft-foot distortion.

Vibration velocity monitoring conforms to international standard ISO 10816, with root-mean-square operational vibration velocities remaining below 2.3 mm/s during full-load production runs.
