AC Motor Product Range

Energy-Efficient AC Motors: YE3, YE4 and YE5

PUTAI YE-series motors are designed for industrial equipment requiring reliable three-phase AC power. The range includes IE3 and IE4 efficiency options, as well as the YE5 high-efficiency motor series.
YE3 Motors: Suitable for general industrial drives, including pumps, fans, compressors, and other continuously operated equipment.
YE4 Motors: Designed for applications with higher motor efficiency requirements, particularly where operating hours and energy consumption are important procurement considerations.
YE5 Motors: Intended for industrial applications where high motor efficiency is a key requirement.

Variable-Frequency AC Motors: YVFE2, YVFE3, YVFE4 and YVFE5

PUTAI YVFE motors are designed for variable-frequency drive systems. They support industrial equipment that requires adjustable speed, process control, or operation under changing load conditions.
The series covers different efficiency levels and power requirements. Selection should consider the motor's operating frequency range, cooling arrangement, torque characteristics, and compatibility with the inverter.

Wound-Rotor AC Motors: YR

PUTAI YR wound-rotor motors are designed for industrial drives where starting characteristics and load requirements make a wound-rotor design suitable.
They can be considered for heavy-duty equipment and applications involving substantial starting loads. Project evaluation should include the driven machine, starting method, load inertia, operating cycle, and associated control equipment.

Technical Considerations for AC Motor Projects

Selecting an AC motor requires more than matching rated power. The following technical factors help determine whether a motor is suitable for the equipment and operating conditions.

Electrical requirements

Rated voltage, frequency, phase, rated current, power, and speed must match the available power supply and driven equipment. For variable-frequency applications, the operating frequency range and inverter characteristics also need to be considered.

Load and operating conditions

The motor should be matched to the driven machine's starting torque, load inertia, operating cycle, and speed requirements. Continuous operation, frequent starting, and variable-load conditions can lead to different motor requirements.

Mechanical installation

Frame size, mounting arrangement, shaft dimensions, coupling, and overall installation space are important for both new equipment integration and replacement projects. Dimensional compatibility should be evaluated against the existing equipment or mechanical drawings.

Cooling and protection

Cooling method and enclosure protection should reflect the installation environment, ambient temperature, ventilation conditions, dust, moisture, and other site factors. These requirements are particularly important for motors installed in enclosed or demanding industrial environments.

Industrial Applications

PUTAI AC motors serve a range of industrial equipment and operating environments.

Pumps and water systems

Motors for water supply, circulation, industrial process pumps, and other fluid-handling equipment.

Fans and blowers

AC motors for ventilation, air handling, industrial exhaust, and process airflow systems.

Compressors

Motors for industrial air and gas compression equipment, with requirements determined by load and operating conditions.

Manufacturing equipment

Motors for production machinery, conveyors, and general industrial transmission systems.

Heavy-duty industrial drives

Wound-rotor motors for equipment requiring suitable starting characteristics and load-handling capability.

Variable-speed process equipment

YVFE motors for applications where speed adjustment is required to support process control and operating efficiency.

Manufacturing Capability and Quality Assurance

Manufacturing Capability

PUTAI's motor manufacturing operations cover a 200,000 m² plant and are supported by RMB 80 million in fixed assets. The company has more than 120 employees, including 18 technical engineers, and over 25 years of motor industry experience.
The manufacturing process covers key stages of AC motor production, including silicon steel preparation, copper winding, insulation treatment, vacuum pressure impregnation (VPI), drying, motor assembly, and dispatch testing.

These processes support the production of motors for different industrial applications, power requirements, and project configurations.

Quality Assurance

Motor quality control involves inspection and testing at relevant production stages. Key areas include winding and insulation work, assembly quality, electrical performance, and final motor testing.

Dispatch testing provides a final check of the motor before delivery. Inspection and test records can support project documentation and equipment acceptance requirements, according to the product and order scope.

OEM Supply and Replacement Motor Matching

PUTAI supports AC motor supply for equipment manufacturers, distributors, system integrators, project contractors, and industrial maintenance teams.

OEM equipment supply
For new equipment projects, motor requirements can be evaluated against the driven machine, installation arrangement, electrical system, operating conditions, and project specifications. This helps align the motor with the equipment design and integration requirements.

Replacement motor matching
For replacement enquiries, the existing motor's nameplate data and mechanical dimensions are important starting points. Matching may involve:
Rated power, voltage, frequency, current, and speed
Motor frame size and mounting arrangement
Shaft diameter, shaft extension, and coupling dimensions
Cooling method and enclosure protection
Starting method, speed control, and operating duty
Installation space and driven equipment requirements
A replacement motor should be assessed against the complete operating and installation requirements rather than rated power alone.

Project and technical documentation
Depending on the order and project requirements, relevant documentation may include motor data sheets, outline drawings, wiring diagrams, nameplate information, and inspection or test records.

For a more accurate assessment, buyers can provide the existing motor nameplate, technical specification, dimensional drawing, or equipment information. These details help establish the required motor configuration and identify potential differences between the existing unit and the proposed replacement.
