Product Features
The air-cooled electromagnetic eddy current brake, equipped with forced ventilation, retains the advantages of water-cooled designs, such as high braking torque and simple operation:
The cooling system is simplified, eliminating the need for large water tanks, pumps, and pipelines, while avoiding freezing problems in cold climates.
It prevents scaling and corrosion issues, ensuring that the air gap remains stable and braking torque remains reliable.
It avoids the risk of coil burnout caused by operator error in water-cooled systems (e.g., failing to start the water pump).
It eliminates failures caused by seal leakage, which can lead to coil damage and bearing breakdown in water-cooled brakes.
Continuous forced ventilation allows effective heat dissipation even after braking stops, unlike water-cooled brakes where cooling ceases once rotation ends, ensuring safer operation during drill-in.
Engineered for drilling rig safety systems, combining durability, safety, and compliance with API 7K, IEC, ISO 9001 and Chinese standards.

Frequently Asked Questions (FAQ)
What are the primary specifications of the MTDSF-50 Eddy Current Brake?
The MTDSF-50 model features a rated braking torque of 55,000 N·m, supports an applicable drilling depth of up to 5,000 meters (with a 5″ drill pipe), and includes 4 coils configured in a series-parallel connection.
Why is the air-cooled system preferred over water-cooled designs?
The air-cooled system eliminates the need for large water tanks, pumps, and complex piping. This prevents freezing issues in cold climates, avoids scaling and corrosion, and eliminates risks associated with seal leakage or operator errors like failing to start the water pump.
How does the cooling system handle heat dissipation after rotation stops?
Unlike water-cooled systems that stop cooling once rotation ends, this model features continuous forced ventilation (with a cooling airflow of 12,000 m³/h). This allows effective heat dissipation even after braking has ceased, ensuring safer operations during drill-in.
What safety and quality standards does this electromagnetic brake comply with?
The brake is engineered for drilling rig safety systems and fully complies with API 7K, IEC, ISO 9001, and Chinese industry standards. Third-party witness and inspection reports are available from organizations like Bureau Veritas (BV), CCS, ABS, and SGS.
What are the electrical requirements for the MTDSF-50 excitation system?
It has a maximum excitation power of 15 kW and a maximum excitation current of 45 A. The rated resistance per coil is 6.54 Ω ±10% with a Class H insulation rating.
