ELECTRO MAGNETIC BRAKES
Brake Type (60% POWER RATING)
✓ Permanent magnet direct-drive eliminates gearbox losses — up to 95% motor efficiency vs. 85–88% for induction motors
✓ Zero-speed starting capability — full torque available from 1 RPM, ideal for viscous crudes and stuck-pump recovery
✓ Integrated Variable Frequency Drive (VFD) with closed-loop torque and speed feedback for real-time production optimization
✓ Electromagnetic braking system — automatic backspin protection, fail-safe engagement on power loss or emergency stop
✓ Heavy-duty double-row tapered roller bearings — sealed for life, no field lubrication required
✓ Built-in SCADA / Modbus RTU interface as standard — full telemetry including torque, speed, temperature and power factor
✓Compact low-profile design — reduced surface footprint, compatible with existing wellhead infrastructure
✓ NEMA, IEC and ATEX / IECEx Zone 1 certified options for hazardous area installations
