2. Versatility

The YD2 motor stands out for its versatility, making it suitable for a broad spectrum of applications. Whether it's conveyors, pumps, fans, or compressors, this motor proves to be an ideal choice for industries requiring a reliable and efficient motor for diverse functions.

Troubleshooting: Rotor Stops Rotating and Smokes

1. Sudden Increase in Load: If the hydraulic motor's load exceeds approximately twice its rated load or faces a sudden blockage, the motor may stop. However, unless the overload or blockage persists excessively, it will primarily overheat rather than produce smoke.

2. High-Power Motor Start-up: When other high-power motors on the same grid initiate, the starting current's magnitude may cause a voltage drop, leading to other running motors' cessation. However, once the line voltage stabilizes, the stopped motor should resume its operation, indicating the issue isn't due to consistently low power supply voltage.

3. One-Phase Open Circuit: A potential issue could arise from a one-phase open circuit in the power supply line specific to the oil motor. Depending on the stator's winding configuration—either △ (delta-shaped) or Y-shaped—one open phase can lead to insulation damage or combustion in varying degrees across the winding phases.
