The YZP metallurgical crane frequency conversion motor from Dalian No. 2 Electric Motor Factory is specifically designed for special working conditions such as metallurgy and crane operations. 0411-66368522 Below is its detailed introduction:

• Technical Parameters
  • Outline Dimensions: Center height 112-450mm.
  • Power Rating: 2.2-900kW.
  • Rated Voltage: 380V, other voltages such as 400V, 440V, 460V, etc., can also be determined based on requirements.
  • Rated Frequency: 50Hz, also supports 60Hz, etc.
  • Speed Regulation Range: 3-100Hz, with 3-50Hz for constant torque operation and 50-100Hz for constant power operation (for 4-pole motors of frame size 355 and motors of frame size 400, constant power operation is from 50-70Hz).
  • Protection Class: Basic protection class is IP44, can also be made as IP54, IP55, IP56 as needed.
  • Insulation Class: Class F or H.
  • Connection Method: Generally, frame sizes 250 and below are Y-connected, frame sizes 280 and above are Δ-connected.
  • Duty Cycle: The reference duty cycle is intermittent periodic duty S3, with a load duration rate of 40%.
• Product Features
  • Wide Speed Regulation Range: Under open-loop U/f control, a speed regulation range of 3-100Hz can be achieved; under vector control, the speed regulation range can be further expanded, with constant torque operation range from base speed to zero speed.
  • Strong Overload Capacity: At rated voltage and rated frequency, it can withstand 200% overload of rated torque for 1 minute; starting torque at low frequency (around 1Hz) can reach 150% of rated torque.
  • Diverse Cooling Methods: Cooling method is IC416 (totally enclosed, axial fan cooling), can also be made as IC411 (totally enclosed, self-fan cooling) or IC410 (totally enclosed surface self-cooling) as needed.
  • Flexible Mounting Types: Basic mounting types are IMB3, IMB5, IMB35, and other mounting types can be derived based on these three basic types.
• Application Scope: Suitable for driving various types of crane machinery and other similar equipment, especially for equipment that operates for short periods or intermittently, with frequent starting, braking, occasional overload, and significant vibration and impact.
