OEM Supply and Replacement Matching
OEM Supply
PUTAI supports motor integration for new equipment. Key requirements include:
Power, voltage, frequency and speed
Frame, mounting and installation dimensions
Shaft extension and coupling interface
Cooling, protection and operating duty
Drawings and inspection requirements
Published customization options include outline dimensions, rated power and operating voltage for applicable projects. Approved specifications and drawings help maintain consistency for repeat orders.
Replacement Matching
For existing installations, PUTAI can assess potential replacement configurations using the original motor model, nameplate, electrical ratings, mounting dimensions, shaft interface, cooling arrangement and operating conditions. J and JS series motors are identified as potential replacement references, but compatibility must be checked against the actual installation.
Providing the nameplate, outline drawing and installation dimensions helps clarify replacement requirements.
Distributor Support
PUTAI supplies industrial motors, drives, spare parts and accessories to international markets. Product availability, order quantities and delivery arrangements are confirmed for each inquiry.
Manufacturing Capability
PUTAI's company profile lists a factory area exceeding 200,000 m², fixed assets exceeding RMB 80 million, more than 120 employees including 18 technical engineers, and over 25 years of motor industry experience.
Its published production process includes silicon-steel preparation, copper winding, insulation treatment, VPI treatment and drying, assembly, and testing before dispatch. The applicable process depends on the approved motor design.
Quality Assurance and Inspection
PUTAI's order process includes manufacturing and intermediate inspection, testing, packing and after-sales service. Inspection activities and acceptance criteria are agreed according to the selected motor, applicable standards and customer requirements. Additional requirements, such as witnessed or third-party inspection, should be specified during technical clarification.
Technical Documentation
Depending on the motor and agreed supply scope, available documentation may include:
Motor technical data sheet
Outline and installation drawings
Shaft and mounting dimensions
Electrical connection information
Applicable inspection and test reports
Nameplate and rating information
Project-specific technical documents
Required documents should be identified before order confirmation.
