Application：Aerial Work Platform


Designed to meet the demands of heavy-duty industrial loads, this series-wound DC motor—featuring a 127mm outer diameter—delivers exceptional overload capacity and robust power. Unlike standard permanent magnet motors, it utilizes a wound-field excitation system (series-wound configuration), enabling the generation of massive starting torque—ideal for driving high-inertia loads. With a peak power output of up to 4.5 kW and a rated torque of 14 N·m, the motor maintains powerful performance even within low-voltage systems (24V or 48V).
Regarding thermal management and insulation, the motor employs high-standard Class H insulation materials; this allows it to withstand elevated internal operating temperatures and supports continuous, heavy-duty industrial operation. While its IP23 protection rating prioritizes internal ventilation and cooling, the motor’s robust mechanical rigidity ensures low vibration (<5 mm/s) and high reliability, even under harsh operating conditions. It serves as a core drive component for applications such as electric forklifts, aerial work platforms, and construction machinery. Supporting a short-time duty cycle (S2) of up to 12 minutes and a 20% duty cycle (ED) for intermittent operation, the motor ensures consistent power delivery during strenuous tasks, acting as a reliable "heart" for high-power industrial equipment.
