The YP2E series metallurgical crane frequency conversion braking motor from Dalian Second Electric Motor Factory is an integrated drive device specifically designed for harsh working conditions such as metallurgy and crane operations. Below is a detailed introduction:

• Technical Parameters
  • Voltage Rating: Available in low-voltage specifications such as 380V/660V, with customizable 1140V to suit mining and metallurgical voltage scenarios.
  • Power Range: 7.5kW-315kW, capable of meeting the power requirements of small to medium-sized crane lifting and traveling mechanisms.
  • Braking Performance: Equipped with a built-in normally closed electromagnetic brake, with a braking torque of 1.5-3 times the rated torque. Braking is activated immediately upon power loss, with a braking response time of ≤0.2 seconds.
  • Protection Rating: Default IP55, with an optional IP65 rating, capable of withstanding harsh environments such as dust and water splashes in metallurgical workshops.
  • Insulation Class: Class F, with windings made of corona-resistant enameled wire, capable of enduring high-temperature environments of 40-60°C in metallurgical workshops while resisting aging erosion of winding insulation caused by high-frequency harmonics from frequency converters.
  • Duty Cycle: Primarily S3 intermittent periodic duty cycle, with connection duty cycles (JC%) of 15%, 25%, 40%, 60%, etc. S4/S5 duty cycles are also available.
  • Installation Method: Available in both horizontal and vertical configurations. Horizontal installation suits rail traveling mechanisms, while vertical installation suits drum-type lifting mechanisms, eliminating the need for base modifications.
• Product Features
  • Integrated Frequency Conversion and Braking Design: The motor’s rear end integrates an electromagnetic brake, designed with a "power-off braking, power-on release" mechanism. Compared to traditional "motor + external brake" solutions, this reduces components such as couplings and mounting brackets, cutting failure points by over 40%.
  • Strong Impact and Overload Resistance: The motor rotor uses a "high-resistivity cast aluminum rotor," with short-term overload capacity reaching 200% of the rated current for 10 seconds and a maximum torque of 2.5 times the rated torque, enabling it to handle impact loads during crane lifting operations.
  • Design for Harsh Environments: The IP55-rated housing features a "labyrinth seal" to prevent iron oxide dust from entering the motor. Additionally, the motor has a built-in vertical cooling fan to dissipate heat even during low-speed operation. Windings are treated with "anti-corrosion, anti-moisture, and anti-mold impregnation," and brake friction plates are made of asbestos-free material resistant to temperatures up to 300°C, protecting against acidic gas corrosion in metallurgical workshops and condensation issues caused by temperature differences in winter.
• Application Scenarios
• Metallurgical Workshop Cranes: Such as bridge cranes in steelmaking workshops, gantry cranes in rolling mills, and grab bucket cranes in coking workshops. These motors can handle high temperatures, dust, and frequent start-stop conditions in metallurgical environments.
• Heavy-Duty Mining Lifting Equipment: Such as mine shaft hoists and port container cranes. Custom 1140V models are suitable for mining power grids, with high torque enabling heavy-load startups. Optional IP65 protection and corrosion-resistant coatings adapt to harsh environments like salt spray.
• Auxiliary Lifting for Heavy Machinery: Such as forging cranes in heavy machinery factories and gantry cranes in shipbuilding workshops. These motors meet the demands of large impact loads during forging operations and the protection requirements of open-air environments in shipbuilding workshops.
