Magnetic Powder Dynamometers/Powder Brake Dynamometers

The solution of Magnetic Powder 동력계 is a testing device that uses magnetic powder to generate braking torque. This dynamometer is particularly suitable for testing motors, transmissions, and machinery that require high torque at low or medium speeds. It provides full torque at zero speed and offers precise control over braking force.

Operating Principle

1. Magnetic Powder Technology: Fine magnetic powder is placing between the rotor and stator.
2. Electromagnetic Field: Electrical current through the coil generates a magnetic field.
3. Torque Generation: Magnetic powder changes its properties under the magnetic field, creating smooth braking torque.
4. Frictionless Operation: Torque is transmitting without mechanical contact, reducing wear.
5. Precise Control: Torque is infinitely adjustable via the excitation current.

Product Range:

1. Torque Range: 1 Nm to 1000 Nm (depending on model).
2. Power Absorption: 250 W to 48 kW (short-term or continuous operation).
3. Speed Range: Up to 4000 RPM for most models.
4. Cooling Options:
   • Air-cooled for compact setups.
   • Water-cooled for high-power applications.
   • Compressing air or blower cooling for extending durability.
5. Accuracy Ratings: ±0.2% to ±0.5%, depending on size and configuration.
6. Compact Design: Low inertia and dynamically, which balances rotors ensure stable performance.

Test Capabilities

1. Torque Testing: Measures real-time torque output with high precision.
2. Speed Testing: Evaluates motor performance across various speeds.
3. Power Testing: Calculates input and output power for efficiency analysis.
4. Efficiency Testing: Determines energy conversion rates under load conditions.
5. Temperature Rise Testing: Monitors heat generation during operation.
6. Load Characteristics Testing: Analyzes motor performance under varying loads.
