Engineered to integrate seamlessly with Permanent Magnet Generators (PMG) and renewable energy matrices.
Unlocking unmatched efficiency and reliability across industrial, marine, and energy storage landscapes.
The global shift toward decarbonization has accelerated the demand for high-efficiency motion and power generation systems. At the center of this transformation lies the Permanent Magnet Synchronous Motor (PMSM) and Permanent Magnet Generator (PMG). Unlike traditional induction motors, permanent magnet systems eliminate rotor copper losses, providing outstanding torque density, exceptional low-speed performance, and a vastly reduced physical footprint. This makes them crucial for specialized industrial applications, electric vehicles, marine propulsion, and wind energy systems.
However, the real-world efficiency of a permanent magnet motor or generator is heavily reliant on the quality and synchronization of the power electronics driving it. Dynamic shifts in load, magnetic saturation challenges, and back-electromotive force (Back-EMF) require advanced, high-performance inverters and bidirectional converters. As a premier OEM/ODM Permanent Magnet Motor Factory & Supplier, Jinan Deming Power Equipment Co., Ltd. builds the electrical architectures and controller technologies that allow these motors to function at peak performance under extreme operational stress.
From core electromagnetic design to high-power grid integration.
We design custom rotor structures (interior vs. surface-mounted permanent magnets) to optimize saliency ratios and torque outputs based on the customer's mechanical duty cycle.
For high-power Permanent Magnet Generators (PMG), our AC/AC converters supply precise line-side regulation and advanced dynamic brake chopper capabilities to mitigate overvoltage spikes.
We provide seamless integration with our bidirectional DC/DC converters and hybrid storage inverters, facilitating real-time energy arbitration in Microgrid settings.

Proven deployments under demanding environments globally.
Salt mist and high humidity require robust anti-corrosion materials. In remote island setups, our 10kW IP54 Waterproof Wind Turbine Generator connects directly to our off-grid AC/DC converters, providing clean power despite harsh sea weather.
Modern vessels utilize onboard permanent magnet auxiliary generators. Our 800KVA to 1000KVA shore power converters adapt land grid frequencies (50Hz/60Hz) to shipboard distribution networks, reducing idling emissions in ports.
Heavy machinery operating far from the primary utility relies on decentralized energy storage. Deming's 300kW Bidirectional Power Conversion Systems (PCS) manage peak shaving and transient loads for permanent magnet conveyor motors.

Designed for hassle-free integration with global utility grids.
Our system solutions strictly adhere to international grid connection codes, including VDE-AR-N 4105 (Germany), IEEE 1547 (US), and AS4777 (Australia) to guarantee smooth grid interaction.
We manufacture system housings designed to withstand mechanical vibrations, seismic events, and thermal shocks, keeping critical controls operational under high mechanical stress.
We support engineers throughout their project's lifecycle, providing detailed commissioning diagrams, remote diagnostic support, and field modification guidelines.
Detailed answers to direct questions from electrical engineers and system integrators.
Our converters integrate hardware-based overvoltage sensing circuits paired with rapid response dynamic brake choppers. In the event of a sudden utility grid drop or converter shutdown, our system redirects the excess kinetic energy generated by the motor into power resistor banks, protecting internal components.
General-purpose VFDs are typically built for basic induction motors and often experience higher switching losses. Deming's AC/AC converters are specifically programmed with field-oriented vector control (FOC) algorithms optimized for PMSM back-EMF profiles. This reduces harmonic distortion and cuts internal losses to achieve up to 99% conversion efficiency.
We provide IP54 to IP67 protection ratings, corrosion-resistant outer coatings, gold-plated connectors, and marine certifications upon request. Our systems are engineered to handle high vibrations and extreme ambient conditions typical of shipboard environments.
Yes. We offer robust communication options, including Modbus RTU/TCP, CANopen, Profinet, and EtherCAT. This allows integration into any SCADA network for real-time monitoring of voltage, active power, current, and thermal telemetry.
High-capacity solutions designed for industrial battery storage and microgrids.
