Sunvim Motor
Sunvim Motor
Engineered for high starting torque and low starting current constraints in heavy industries. Fully compliant with Canadian grid criteria and local electrical standards.
The Greater Toronto Area (GTA) and Southern Ontario represent Canada's economic engine. From heavy metallurgy and chemical manufacturing in the Golden Horseshoe to large-scale municipal clean water treatment systems, high-torque electric motors are essential to keeping critical processes active. In these environments, starting massive loads like compressors, crushers, grinders, and pumps poses a severe electrical and mechanical challenge to local municipal grids managed by organizations like Toronto Hydro and Hydro One.
This is where Slip Ring Motors (Wound Rotor Induction Motors) offer exceptional performance. By allowing external resistance to be connected to the rotor circuit, they deliver unmatched starting torque under load while limiting damaging inrush currents. Our products are specially adapted to meet the challenges of Southern Ontario's industrial sectors, operating reliably under extreme temperature swings (ranging from humid summer highs to winter lows of down to -40°C) with standard-setting thermal efficiency and IP55/IP56 class protection profiles.

Decades of continuous engineering advancements form the foundation of our high-quality electric motor production.
Gaomi Electric Appliance Factory was officially established, focusing on basic electrical equipment and starting systems. Later renamed as Weifang Electric Machinery Factory in 1988.
Mr. Sun, then the visionary director, founded Gaomi Towel Factory, which served as the operational predecessor for the massive Sunvim Group conglomerate.
Weifang Electric Machinery Factory was formally acquired by Sunvim Group, leading to the creation of Shandong Sunvim Electrical Machinery Co., Ltd. and a massive upgrade of our motor production lines.
Completion of a state-of-the-art modern factory within the Sunvim Industrial Park. Officially renamed Shandong Sunvim Motor Co., Ltd., incorporating smart manufacturing lines for global markets.
Our rugged wound rotor and industrial induction motors are deployed across key sectors in Canada and globally, operating reliably in the most demanding process environments.
Deploying major electrical hardware in Canada requires strict adherence to regional safety codes and national performance baselines. Every slip ring and induction motor shipped to Ontario is engineered to satisfy or exceed CSA (Canadian Standards Association) C22.2 No. 100 benchmarks for electric motors, in addition to the strict regulatory mandates of the Ontario Electrical Safety Authority (ESA).
Our global engineering protocols align with both NEMA and IEC standards, providing drop-in mechanical dimensional compatibility alongside customized termination setups. Whether you need a specific type of winding insulation (Class F/H) or a specialized enclosure protection scheme (IP55/IP56/IP65), Sunvim motors are customized to handle the toughest local operational environments.
As industries implement smart technologies and strive for carbon neutrality, electric motors are evolving into highly intelligent systems. The Shandong Sunvim R&D pipeline is continuously integrating state-of-the-art telemetry to meet the future demands of Canadian and international plants.
Integrating vibration sensors, bearing temperature probes (RTDs), and stator temperature telemetry directly into the frame. This enables real-time diagnostic reporting over Modbus or EtherNet/IP, minimizing unplanned downtime in critical pulp, paper, and mining operations.
Innovating low-loss carbon brush chemistry alongside custom-alloy slip rings. This reduces spark production, increases brush longevity in heavy-duty cycles, and dramatically lowers carbon dust generation, reducing maintenance frequency.
Combining traditional starting torque benefits with high-efficiency stator lamination profiles. Our upcoming drive systems optimize energy efficiency to comply with energy consumption policies across Canada.
