4. Setup and Installation
The Marsrock Permanent Magnet Generator produces three-phase AC output. Its output wires are non-polar, meaning the connection order of the three wires does not affect the output direction of voltage and current. For proper operation and charging, it is essential to connect the generator to a suitable charge controller, such as the Marsrock WT060 MPPT charge controller, and then to a battery bank.
4.1 Wiring Diagram
Refer to the diagram below for a typical wiring setup. Ensure all connections are secure and properly insulated.
Figure 5: Example wiring diagram for the generator with a WT060 charge controller and battery.
The WT060 charge controller (or similar compatible model) is crucial for converting the AC output to DC, regulating the voltage, and protecting the battery from overcharging. For more information on the WT060 controller, please refer to its dedicated manual.
4.2 Mounting the Generator
The generator comes with an integrated base for stable mounting. Secure the base to a rigid surface using appropriate fasteners. Ensure the shaft is aligned with the driving mechanism (e.g., wind turbine hub, pulley system) to prevent undue stress on the bearings.

5. Operating Instructions
The Marsrock PMG generates electricity when its rotor rotates within the permanent magnetic field. To achieve stable current output, the generator must rotate continuously and stably at a sufficient speed. The output voltage and current are directly related to the rotational speed.
5.1 Power Generation Principle
The pure copper coil within the generator outputs voltage as it rotates. The direction of rotation does not affect the output direction of its voltage and current due to its three-phase AC output. For optimal performance, aim for a stable rotational speed close to the rated speed of your specific application.
5.2 Applications
This generator is versatile and can be driven by various power sources:
- Wind Power: Ideal for wind turbine generators.
- Water Power: Can be used in hydro generators.
- Motor Driven: Suitable for test plants or motor-driven systems via a belt.
- Human Power: Applicable for exercise bikes or other human-powered devices.

6. Maintenance
The Marsrock Permanent Magnet Generator is designed for durability and a long service life of 20 years, requiring minimal maintenance. However, regular checks can ensure optimal performance:
- Visual Inspection: Periodically inspect the generator for any signs of physical damage, loose connections, or corrosion.
- Cleanliness: Keep the exterior of the generator clean and free from dust, dirt, and debris to ensure proper heat dissipation.
- Connection Integrity: Verify that all electrical connections are tight and secure.
- Shaft and Bearings: Ensure the shaft rotates freely without excessive play. While designed for longevity, listen for unusual noises that might indicate bearing wear over extended periods.
7. Troubleshooting
If you experience issues with the generator's output, consider the following:
- Low or No Power Output:
- Check Rotational Speed: The generator requires a stable and sufficient rotational speed to produce adequate current. If the speed is too low or unstable, you may only obtain voltage without significant current.
- Verify Connections: Ensure all three output wires are correctly connected to the charge controller and that the controller is properly connected to the battery.
- Inspect for Obstructions: If used with a wind turbine, check for any obstructions preventing the blades from rotating freely.
- Unusual Noises or Vibrations:
- Check Mounting: Ensure the generator is securely mounted and that there is no wobble or misalignment with the driving mechanism.
- Inspect Bearings: While rare, worn bearings can cause noise. If persistent, professional inspection may be required.
- Overheating:
- Ensure Ventilation: Confirm that the generator's housing is not obstructed, allowing for proper airflow and heat dissipation.
- Check Load: Ensure the load connected to the system does not exceed the generator's maximum output capacity.
