High Voltage Motor Slip Ring AC Motor Spares

PUTAI supplies copper slip rings for high-voltage wound-rotor AC motors, with listed inner diameters of 55–145 mm and outer diameters of 120–250 mm. The product serves motor OEMs, spare-parts distributors, repair companies and industrial maintenance teams requiring component supply or replacement matching.

Steel Mills and Metallurgical Plants
Wound-rotor motors may drive mill auxiliaries and material-handling equipment in steel production. Compatible slip rings may be required for motor repairs and maintenance of existing drives.

Mining and Mineral Processing
Wound-rotor motors may operate crushers, grinding mills and conveyors. Replacement slip rings may be needed where the installed motor uses a compatible design.

Cement Production
Cement plants use motor-driven crushers, mills, conveyors and large fans. Slip rings may be required as maintenance spares for compatible wound-rotor motor systems.

Power Generation and Industrial Utilities
Large motors may drive auxiliary pumps, fans and other utility equipment. Replacement requirements depend on the original motor design and component specifications.

PUTAI supports OEM component inquiries and replacement requirements for existing industrial motors. Buyers can submit technical drawings, component specifications or details of the existing motor to help define the required slip ring.

OEM Component Supply
OEMs and equipment manufacturers can submit drawings or technical specifications for review. Relevant information includes:
Motor model and component reference
Shaft or mounting interface dimensions
Inner, outer and axial dimensions
Material grade and surface requirements
Current or circuit requirements, where applicable
Drawing tolerances, quantity and delivery schedule
For repeat orders, the approved drawing and agreed specification can serve as the reference for subsequent supply. Changes to materials, dimensions or acceptance criteria should be agreed upon before production.

Replacement for Existing Motors
For maintenance teams, repair companies and spare-parts distributors, the original component can help establish replacement requirements when drawings or part numbers are unavailable.
Please provide the following where available:
Motor manufacturer, series and model
Motor nameplate photo
Photos of the existing slip ring
Available dimensions and mounting details
Original drawing or previous part specification
Required quantity and target delivery date
If information is incomplete, the available details can be reviewed to identify what additional measurements or documentation are needed. Physical samples may also be assessed if their condition permits reliable measurement.

Related Motor Series and Brand References
The product information references YR, YRKK, YSR, YRKS, JR and YRQ motor series, as well as Shanghai Electric, SIMO, SEC Motor and Wolong.
These references help identify relevant inquiries but do not imply universal interchangeability. Compatibility must be established using the specific motor and component requirements.

Custom Requirements and Order Confirmation
For non-standard requirements, the final specification should define the applicable dimensions, material, tolerances and other technical requirements. Any material substitution or deviation from the original drawing must be agreed upon before production.
Minimum order quantity, lead time, documentation and delivery terms should be confirmed in the quotation.

PUTAI Electric Motor Equipment Co., Ltd. manufactures industrial motors and related electrical equipment, including AC motors, DC motors, medium-voltage motors, starters and drives, motor windings and motor components.

Inspection requirements should be based on the approved drawing, specified material and agreed acceptance criteria. Depending on the order, they may include:

Material verification: Checking the specified copper or copper-alloy grade.

Dimensional inspection: Checking designated dimensions against the approved drawing.

Surface inspection: Assessing the component against agreed surface requirements.

Technical documentation: Confirming requirements for material records, dimensional reports or other supporting documents.

Inspection methods, acceptance criteria and required documents should be agreed upon before production.
