MDSP Series Variable Frequency Speed Regulation Three-Phase Asynchronous Motor 0411-66368522 Dalian Motor Factory MDSP Variable Frequency Motor YSPA Series Variable Frequency Motor

Dalian Motor Factory's MDSP Series variable frequency motor is an AC variable frequency motor with multiple advantages and a wide range of applications. Below is a detailed introduction:

• Technical Parameters:
  • Voltage Level: 380V/690V, compatible with mainstream industrial power grids.
  • Power Range: 0.75-2800kW, with the MDSP/S series (water-cooled) power range reaching 0.75-3500kW, meeting the needs of different power equipment.
  • Center Height: 80-630mm (MDSP), 80-710mm (MDSP/S), adaptable to various installation spaces.
  • Frequency Parameters: Rated frequencies include 25Hz, 33Hz, 50Hz, 100Hz, etc., with a frequency adjustment range of 2-100Hz, 2-200Hz, 2-300Hz (for some specifications).
  • Protection Level: IP55, dustproof and splash-proof, meeting the requirements of most industrial environments.
  • Insulation Class: Class F, temperature resistance up to 155°C, capable of withstanding short-term high temperatures during variable frequency operation.
• Product Features:
  • Wide Speed Range and Low-Speed Stability: Frequency adjustment range covers 2-300Hz, with some specifications having no torque pulsation at 2Hz and torque fluctuation ≤5%, meeting various speed requirements from precision conveying to high-speed mixing, ensuring smooth equipment operation.
  • High Starting Torque and Low Starting Current: Starting torque can reach 1.8-2.2 times the rated torque, enabling direct drive of heavy-load equipment startup without additional starting devices; meanwhile, the starting current is only 1.5-2 times the rated current, much lower than traditional asynchronous motors, avoiding grid impact during startup.
  • Low Noise and Low Vibration: Utilizes optimized electromagnetic design and rotor dynamic balance, with a balance grade ≤G2.5; operating noise is 3-5dB(A) lower than traditional motors of the same power, and vibration speed ≤1.8mm/s, suitable for noise-sensitive scenarios.
  • Special Design: The MDSP/S series adopts a vertical water circulation cooling system, solving heat dissipation challenges in environments with thin air or poor air circulation, keeping the motor temperature rise within the allowable range of Class F insulation.
  • Control Flexibility: Supports the addition of incremental or absolute encoders to form a speed closed-loop control system with the frequency converter, achieving speed regulation accuracy of ±0.1%; also allows for custom base frequencies to meet the frequency requirements of special equipment.
• Applicable Scenarios:
  • General Industrial Transmission Scenarios: Such as conveyor belts, fans, water pumps, compressors, mixers, and general machine tools. Its voltage, protection level, and wide speed range meet the full-process operational needs of equipment.
  • High-Power Heavy-Load Transmission Scenarios: Suitable for mining crushers, metallurgical rolling mills, large fans, port cranes, etc. High starting torque enables heavy-load startup, and the MDSP/S series water-cooled design adapts to harsh environments.
  • Enclosed / Special Environment Scenarios: In environments such as ship engine rooms, dock cranes, underground mines, and plateau areas, the MDSP/S series water cooling system is unaffected by air circulation and density, ensuring long-term stable motor operation.
  • Precision Speed Regulation Scenarios: Can be used for CNC machine tool spindles, elevator traction machines, servo feeders, packaging machines, etc. With added encoders, it meets equipment requirements for speed stability and positioning accuracy.
