Description
YE Series General-Purpose Three-Phase Asynchronous Motors The YE series from Baolei Electric is a range of general-purpose three-phase asynchronous motors designed for reliable and efficient operation in a wide variety of industrial applications. With a robust electromagnetic design and optimized cooling, YE motors provide stable torque, low noise and good efficiency under continuous S1 duty.
The motors are available in multiple frame sizes and power ratings, with standard three-phase AC supply and 50/60 Hz frequency options to match different regional grids and inverter drives. High-quality silicon steel laminations, precision rotor balancing and F-class insulation help reduce losses and extend service life, even under frequent start/stop and moderate overload conditions.
A durable housing with enhanced protection level and IC411 self-ventilated cooling enables YE motors to work safely in dusty or humid industrial environments. Standard mounting options (foot-mounted and flange-mounted) and flexible terminal box positions make integration into pumps, fans, compressors, gearboxes, conveyors and other machinery straightforward.
With consistent quality, competitive performance and customization options for voltage, frequency, mounting and shaft dimensions, the YE series three-phase asynchronous motors are a cost-effective choice for OEMs and end users seeking a dependable general-purpose drive solution.
