High-efficiency electric motors that deliver measurable energy savings for our customers
Y3 series compact AC motor is one of the high-efficiency and energy-saving high-voltage squirrel cage AC motors. It is divided into Y2 series and Y3 series according to the efficiency level. This series of motors adopts the current internationally popular new design technology of high-voltage three-phase asynchronous motors, combined with our long-term and stable experience in motor design and manufacturing.
The performance and installation dimensions of Y3 series compact ac motor comply with IEC standards, GB755 standards, and relevant professional technical standards. And our company has passed ISO9001 international quality system certification multiple times, controlling the entire process from ordering, development, manufacturing, inspection, sales, to service in accordance with the requirements of ISO9001 quality system.
This series compact ac motors uses high permeability and low loss cold-rolled non oriented silicon steel sheets, resulting in low losses and high efficiency. The electric motor adopts a reliable F-class insulation structure and vacuum pressure (VPI) immersion paint. The temperature rise is designed according to B-class assessment, which extends the insulation aging life. The basic ventilation method for this series of motors is IC411, and the cooling and heat dissipation conditions are relatively mature. This series of electric motors has the characteristics of high efficiency, energy saving, low vibration, low noise, reliable performance, and easy safety and maintenance.
Electric motors are allowed to start directly and with reduced voltage at rated voltage and frequency.
The Y3 series compact ac motor adopts a new generation of advanced high-strength cast iron structure internationally, and the motor frame and end cover adopt high-strength cast iron structure. The exterior of the machine base is equipped with orthogonal distribution - vertically and horizontally distributed heat dissipation ribs, which have good heat dissipation performance, overall rigidity, and durability.
Here is one comparison of compact-type high voltage motor and box-type high voltage motor.
