DC Variable Speed ​​Motor Z4-250-21-185KW-440V-IC06-B3

Robust and durable: cast iron frame, laminated stator magnetic bar with precisely positioned poles for excellent commutation performance

Easy to maintain: modular design, easy brush replacement, high quality bearings from renowned brands, advanced lubrication system to reduce maintenance costs

Safety and reliability: Has a full range of protective functions, can be equipped with overheating, overloading and overvoltage protection devices to ensure safe operation

Excellent dynamic response: Low moment of inertia, can withstand frequent shock loads, support stepless adjustment and automatic speed stabilization, minimum stable speed reaches 20 rpm (under constant torque mode), speed control range is wide up to 1:200

High overload capacity: can withstand short-term overload of 2-3 times the rated torque, low operating noise, efficiency coefficient reaches 90.5% (at 185 kW / 1500 rpm), which meets modern industrial requirements

Flexible adaptability to power supplies: Suitable for both connection to DC power supplies (motor groups) and for operation with static rectifier sources (assuming a 440 V three-phase bridge rectifier, no additional smooth reluctance coils are required), adapted to various control systems

Reliable and stable operation: Copper armature windings and high-precision switching structures, multi-layer impregnated windings have high insulation reliability, can withstand pulsating current and harsh operating conditions, long service life
