Title:
YE4-225M-2 Low Voltage Three Phase AC Motor
Brief Introduction
The YE4-225M-2 AC induction gear motor is engineered for exceptional operational stability, prioritizing precise air gap uniformity between stator and rotor. Consistent air gap is critical to prevent noise, vibration, and catastrophic rotor-stator contact. This AC induction gear motor achieves optimal gap tolerance through meticulous machining of frame register surfaces and precise control over bearing fits and component concentricity, minimizing the unevenness that degrades performance. An excessively large gap increases magnetic reluctance, significantly raising excitation current and losses while reducing power factor. Conversely, too small a gap heightens harmonic losses, noise, and vibration risks, and can diminish starting and maximum torque.
The YE4-225M-2 design carefully balances these factors. Its air gap is maintained within the established range suitable for its size, avoiding the pitfalls of under-sizing (increased harmonic content, losses, noise, reduced torque, reliability concerns) and over-sizing (poor power factor, high excitation losses). This precision ensures efficient electromagnetic coupling for reliable energy conversion, smooth operation, and reduced harmonic-induced losses, making this integrated AC induction gear motor a dependable solution for demanding drives.

Why choose Simo Brand YE4 series of Motor?
The YE4 Series LV Motor has a high-strength cast iron frame, so it is very strong and has a longer service life. Anti-corrosion copper wire coils are not only more powerful but also have thermal protection, so they are safer to operate. The copper wires are evenly arranged, so they are not easy to deform even if the motor runs for a long time. The bearings have high torque and good responsiveness, stable output, and lower noise. In addition, the smaller size and energy-saving characteristics make it more popular.
