Replace the existing asynchronous motor + VFD/electromagnetic drive system with the Panpu SRM series Switched Reluctance Motor Drive (SRD). Designed for underloaded ("big horse pulling small cart") and heavy-load frequent start-stop conditions, it matches motor output to actual load requirements. Overall efficiency exceeds that of AC asynchronous motor VFD systems by more than 3%, and in low-speed conditions, by over 10%. Typical energy savings range from 10% to 50%.
Use Cases
Oilfield pumping units and well testing machines, injection molding machines and extruders, horizontal boring mills and vertical lathes, screw presses and brick pressing machines, ball mills and crushers, fans and pumps with compressors, etc., under variable load conditions, heavy-load starting, frequent forward/reverse rotation, and frequent start/stop operations.
Solve pain points
The motor's rated power far exceeds the equipment's actual operating power, resulting in low efficiency during prolonged light-load operation.High starting torque is required for overloaded or high-inertia equipment; standard induction motors draw 0 to 7 times the rated current, causing grid surges.Motor overheats significantly during low-speed VFD operation; temperature rise compromises insulation life.Frequent load fluctuations and rapid forward/reverse cycling cause accelerated wear and high failure rates in transmission and electrical components.No-load power factor is only 0.2~0.4; additional reactive power compensation equipment is required.Device status is not visible; lack of power consumption and operational data hinders energy-saving decisions.
Solution Composition
Load profile mapping and power matching for selection (0.55~315kW, 750/1000/1500/3000r/min four rated speed options) / Panpu SRM Switched Reluctance Motor (rotor without windings or permanent magnets, H-class insulation, IP54 protection rating) / SRD Intelligent Controller (dual-loop speed and current control, wall-mounted, IP23 protection rating) / Mechanical interface and mounting dimension compatibility (132~355 frame sizes, 1x1 to replace existing mounting locations) / Protection and self-diagnostic configuration (overvoltage, undervoltage, phase loss, overload, stall, overcurrent, output short circuit, overheating) / Digital motor IoT platform integration (real-time monitoring of energy consumption, production capacity, and operating conditions) / On-site installation, commissioning, and operational data acceptance
