Ultra-efficient custom electric motors meeting Morocco's rising demand for green energy transition, lowering overall operational electrical loads.
Morocco is undergoing a historic industrial transformation, spearheaded by mega-scale infrastructure projects, massive mineral processing, and large-scale agricultural water supply programs. As the world's leading exporter of phosphates (represented majorly by **OCP Group** in regions like Khouribga, Benguerir, and Youssoufia), heavy mineral sorting, ball milling, and slurry piping require electric motors that can execute controlled, high-torque startups under maximum load capacity without causing voltage fluctuations in local grids.
Traditional cage induction motors present massive challenges during high-inertia starting phases, drawing up to 600-800% of their rated current. To mitigate grid penalties enforced by Morocco's **ONEE (Office National de l'Electricité et de l'Eau Potable)**, slip ring motors (wound rotor induction motors) are the premier technology. By connecting the rotor winding to external variable resistors, starting current is kept within safe limits, and starting torque is elevated up to 250% of the nominal scale.
Furthermore, mega-desalination facilities in Agadir, Casablanca, and Dakhla, along with complex metallurgical plants in Jorf Lasfar and Nador, utilize custom-built slip ring motors to drive heavy pumps, centrifugal compressors, and mill shredders where continuous, step-by-step startup control is structurally imperative.
| Industrial Sector | Primary Application | Preferred Slip Ring Motor Feature |
|---|---|---|
| Phosphate Mining (OCP) | Ball mills, rotary crushers, conveyor lines | High-inertia starting, dust-proof enclosures (IP55) | Desalination & Irrigation | High-pressure centrifugal pump stations | Step-less startup velocity control via LRS systems |
| Cement Production | Kilns, massive grinding mills | Wound-rotor with dynamic external resistance matching |
| Steel & Metal Mills | Hot-rolling mills, wire drawing benches | Superior heat dissipation & modular structure design |

Slip ring motors (wound rotor motors) allow for step-by-step external starting resistance adjustments. This is essential for high-inertia equipment like phosphate ball mills and heavy conveyors used in Moroccan mining. Unlike squirrel cage motors, which experience massive inrush currents (up to 8 times the nominal rate) and low starting torque, slip ring motors deliver starting torque up to 250% of the nominal rate while maintaining starting currents within 150-200%. This protects local electric grids from voltage drops and saves operating costs.
Our motors are fully customized to meet the strict voltage and frequency parameters of the Moroccan power grid (typically 380V/400V/415V for low voltage and 5.5kV/6kV/6.6kV/10kV/11kV for medium/high voltage systems operating at 50Hz). Additionally, our engineering department designs insulation configurations meeting Class F or Class H safety levels, accompanied by high-grade enclosure protection (IP54/IP55/IP65) to withstand dust, sand, and humidity in local industrial sites.
All Shandong Sunvim electric motors are certified in absolute alignment with international and European directives, holding CE, ISO9001:2015, UKCA, UL, and major marine classification standards (ABS, CCS, DNV). We provide full certificates of conformity, factory routine test reports, and detailed customs clearance documentation to ensure rapid transit through Port Tanger-Med and Port of Casablanca.
Yes. As a comprehensive power solution manufacturer, we can supply fully configured Liquid Resistance Starters (LRS) and electromagnetic starter cabinets tailored to your specific starting cycle, duty rating, and torque demands. This guarantees a single source of design responsibility and optimal performance matching between the slip ring motor and its starting system.
