High-Precision
EMC Testing Turntables
Since 1991, Weizhong has engineered electromagnetic compatibility (EMC) testing platforms, providing low-noise, high-stability heavy-duty rotation for global compliance centers and automotive/aerospace research laboratories.
Optimized for International EMC Compliance
Engineered with full motor chamber shielding and non-conductive parts to eliminate ambient RF noise, maintaining compliance with CISPR 16-1-4 and MIL-STD-461 testing baselines.
Patented Pin-Gear Drive supplies continuous positive engagement, mitigating the positional slip common in friction-wheel alternatives for perfect scan synchronization.
Heavy-duty structural framework holds immense payload balances without tilting or platform deformation, keeping perfect horizontal alignment during long continuous test cycles.
The Weizhong Technical Advantage
✓ Patented Pin-Gear Drive System
Provides superior mechanical output torque and avoids the tracking drift typical in automated anechoic chamber testing setups.
✓ Automated Controller & Encoder Integration
Integrates via absolute encoders with automated laboratory testing systems using standard industrial Ethernet (Profinet, EtherCAT, TCP/IP).
✓ Certified RF Noise Shielding
All motor drive modules and electrical enclosures are fully isolated to remain below emission thresholds dictated by commercial and military validation standards.
EMC Technical Insights & FAQ
Q1: How do you manage electromagnetic noise in the platform?
A: We utilize low-EMI structural engineering, complete localized shielding for motor compartments, and non-conductive isolation barriers to ensure the turntable architecture minimizes ambient RF noise floors below compliance thresholds.
Q2: How does the Pin-Gear system support EMC testing?
A: The mechanical engagement of our patented Pin-Gear drive eliminates the slip, backlash, and frictional heating common in heavy-duty friction drives, ensuring a steady 0.01-degree positioning accuracy vital for multi-axis continuous scan synchronization.
Q3: Can the turntable be used inside shielded chambers?
A: Yes, our systems are fully modularized and optimized for anechoic and shielded chamber integration, with all standard control cables routed through compliant wave-guide filters and electronics housed in RF-shielded control cabinets.
Q4: What control protocols are supported for integration?
A: Our platforms use high-resolution absolute encoders and seamlessly interface with major laboratory software via industry-standard hardware layers, including Profibus, Profinet, EtherCAT, and TCP/IP.
Q5: Can you customize the turntable size and load capacity?
A: Weizhong specializes in heavy-duty customizable engineering, manufacturing rotating platforms ranging from 3 meters to 60 meters in diameter, and handling structural load limits from 500 kg up to 1,000 metric tons.
Q6: Do I need to dig a foundation pit for installation?
A: Not necessarily. Our Ultra-thin Pin-Gear turntable series features a compact 127mm profile height that can be surface-mounted directly onto existing chamber floor structures, eliminating expensive pit excavations.
Q7: What is the expected operational lifespan?
A: The positive rolling contact of the Pin-Gear design experiences negligible mechanical wear compared to friction wheels or traditional internal gears. With basic lubrication intervals, these heavy industrial systems deliver multi-decade lifespans.
Q8: How do you handle international after-sales support?
A: We provide remote engineering diagnostic support, step-by-step video installation blueprints, and modular electrical components to guarantee swift service turnarounds across our active installations in 60-plus countries.
