ODM Pump & Company InfoModern automated machinery dictates an era of absolute safety, zero tolerances for braking latency, and flawless integration with variable frequency drives (VFD). In this paradigm, Magnetbremsen (electromagnetic brakes) have migrated from auxiliary components to core system elements.
According to industrial automation market analytics, the global demand for electromagnetic brake motors is projected to expand significantly, driven by:

Gaomi Electric Appliance Factory was officially established. Later in 1988, our corporate operations scaled and we renamed as Weifang Electric Machinery Factory, introducing automated machinery processes.
Mr. Sun, our visionary factory director, established the Gaomi Towel Factory. This crucial foundation set up the dynamic and diverse conglomerate known today as Sunvim Group.
Strategic integration occurred: Weifang Electric Machinery Factory was acquired by Sunvim Group, giving birth to Shandong Sunvim Electrical Machinery Co., Ltd. and opening global trade links.
Completion of our modernized smart facility within the Sunvim Industrial Park. Rebranded as Shandong Sunvim Motor Co., Ltd., launching optimized robotic integration lines.
Our engineering team addresses standard technical, configuration, and integration queries regarding electromagnetic brake systems.
DC-excited electromagnetic brakes utilize integrated solid-state rectifiers within the terminal junction box to convert AC supply. They offer smoother braking action, compact coil volumes, and high reliability with less coil heating. AC-excited brakes offer extremely rapid actuation times (typically <20ms) and are suited for fast cycling applications, though they demand higher peak inrush currents and are more susceptible to wear.
When operating YEJ brake motors on Variable Frequency Drives, we route the brake rectifier supply through a dedicated terminal source independent of the primary VFD output. This ensures that even when the motor runs at ultra-low frequencies or transitions, the electromagnetic brake receives its required full voltage to maintain disengagement, preventing premature friction pad wear.
Our high-voltage modular motors (such as the Y/YKS/YX series) employ Class F insulation systems with Class B temperature rise margins. Windings are encapsulated through continuous Vacuum Pressure Impregnation (VPI) processes using premium solventless epoxy resins. Additionally, integrated Pt100 RTDs monitor stator and bearing temperatures in real-time, feeding safety limits directly to system controllers.
Yes, torque adjustment is achieved by adjusting the pre-tension on the internal spring mechanism inside the brake housing. By tightening or loosening the adjusted sleeve nuts located behind the manual release handle, the clamping force on the non-asbestos friction discs can be calibrated to fit specific load acceleration deceleration parameters.
Our automatic shaft machining line incorporates precision multi-axis CNC machines and active feedback sensors that analyze tooling wear dynamically. Furthermore, the completed shafts undergo high-precision induction hardening and grinding, followed by three-dimensional coordinate instrument measurements to guarantee shaft concentricity, minimizing motor vibration and noise.
Non-asbestos composite friction materials offer environmental compliance while providing a highly stable coefficient of friction across variable temperatures (up to 150°C). This stability limits torque fade during emergency stops, ensuring predictable stopping distances and reducing mechanical wear under high duty cycles.
We hold certifications from leading global classification societies, including DNV, ABS, CE, and CCS. Our marine-grade motors feature dedicated shaft seals, enhanced anti-corrosion coatings, marine-grade grease, and specialized electrical configurations that meet strict vibration and temperature margins required for ocean-going applications.
Our brakes can be equipped with either manual release hand-levers or automatic electromagnetic release systems. Manual release levers are highly beneficial during commissioning, maintenance, or power failures, allowing operators to manually disengage the brake and rotate the shaft without electrical power.
IE3 Premium and IE4 Super Premium efficiency motors minimize core losses, winding resistance, and windage losses through higher-quality silicon laminations and optimized copper slot fill factors. For large-scale continuous operations (such as water pumps or ventilation systems), upgrading to IE4 can reduce utility power consumption by 2% to 5%, leading to rapid amortization of the initial investment.
Key parameters include verifying the brake air-gap clearance periodically, monitoring the thickness of the friction disc, checking rectifier output voltage, and ensuring the brake housing remains free of grease, dust, or abrasive particles. Operating the brake within its rated cycles and load limits prevents thermal overload and guarantees maximum service life.
