المميزات والفوائد
- Wound rotor with external rotor resistance enables starting torque of 200–250% rated torque while limiting starting current to 150% FLC — critical for large crushers and mills at Saudi mining and cement sites with limited supply kVA.
- External resistance starter connection via slip rings allows acceleration time and torque profile to be adjusted per application by changing resistor values, providing flexibility that software-only solutions cannot match for very large inertia loads.
- Rated voltage range from 380 V to 6600 V in a single motor frame family allows the same motor design to be used at MV distribution voltage levels, avoiding the cost of a dedicated MV VFD for fixed-speed or limited-range applications.
- Robust carbon brush and slip ring assembly with large contact area and accessible maintenance covers allows in-service brush replacement without motor disassembly — reducing planned maintenance downtime at continuous-process Saudi facilities.
- Optional forced ventilation (IC511, IC611) cooling increases thermal capacity for duty-cycle and short-time loaded applications such as crane and hoist motors, allowing a smaller motor frame to handle the thermal demands of intermittent duty.
- PT100 temperature sensors in stator windings and rotor slip ring housing provide continuous thermal monitoring, protecting the motor against the consequences of external resistance controller faults or stalled starts.
- IEC 60034-12 starting category S, D, H available to match the starting requirements of different crusher, mill, and compressor load curves, ensuring motor thermal withstand during the extended start times of high-inertia loads.
التطبيقات الصناعية
- Ball mill and SAG mill main drives at phosphate and mineral processing facilities in Wa'ad Al-Shamal and Ras Al-Khair, where starting torque requirements of 180–220% rated and 20–60 second acceleration times exclude squirrel-cage motor options.
- Primary and secondary crusher drives at Saudi mining operations, where the controlled acceleration of the slip-ring motor protects crusher liners and ore feed conveyor mechanical systems from high-inertia impact loading.
- Raw mill and cement mill main drives at Saudi Cement, YACCO, and Al Jouf Cement plants, where breakaway torque requirements for grinding media exceeding 200% rated torque mandate slip-ring motor starting.
- Container and bulk cargo crane drives at Dammam, Jubail, and Jeddah ports, where controlled acceleration reduces load swing on long wire ropes and gearbox shock loading compared to DOL squirrel-cage starts.
- Kiln trunnion drive motors at cement and lime plants, where the external resistance provides precise low-speed starting capability for controlled kiln shell warm-up procedures during commissioning and restarts.
- Large induced draught and forced draught fan drives at power stations and petrochemical facilities, where the reduced starting current protects the MV bus from voltage dip during starts of motors exceeding 2 MW.
- Marine and offshore lifting equipment drives at Saudi Aramco offshore jackets and IKTVA-qualified Saudi offshore service vessels, where the slip-ring motor's precise speed control via external resistance suits variable-speed crane duty.
