Characteristics

Highlights of the PMG fast excitation rectifier

Rapid excitation of the spring brake: This component allows fast excitation of the spring brake, which means that it can be activated and deactivated quickly. This feature is essential in applications where precise control and immediate response is required.

Reduction of spring brake consumption: The product is designed to reduce the energy consumption of the spring brake. This not only improves system efficiency, but also contributes to brake durability by minimising heat generation.

WAGO terminal connection: This product is equipped with a WAGO terminal connection, which offers significant advantages.
- This includes a faster brake connection, which simplifies installation and maintenance.
- It provides a secure cable fastening no over-tightening or loosening of screws, ensuring a secure and reliable connection.

Application examples

Examples of outstanding applications of the PMG fast excitation rectifier

Rapid excitation of the spring brake:

- Supplied voltage 230 VAC: This product operates on a supply voltage of 230 volts alternating current (VAC). This voltage is used for general brake operation and other related functions.

- Braking coil voltage of 103 VDC: To achieve fast excitation of the spring brake, a specific brake coil voltage of 103 volts direct current (VDC) is used. This lower voltage is essential to activate and deactivate the brake in a fast and controlled manner.

- Optimum brake release by overexcitation of the coil: An outstanding feature is the ability to optimally release the brake by overexciting the coil. This is achieved by applying a release voltage of 205 VDC for 500 milliseconds. This action ensures efficient and reliable brake release when needed.

- Expanded operating airspace: It is mentioned that the permissible operating air gap will be extended by a factor of 2, which means that maintenance intervals will be extended. This contributes to the efficiency and reliability of the brake, as fewer maintenance interventions are required.

Reduction of spring brake consumption:

- Supplied voltage of 230 VAC: As with the fast excitation, the product uses a supply voltage of 230 VAC for general operation.

- VBraking coil voltage of 205 VDC: To reduce the power consumption of the spring brake, the brake coil voltage is set to 205 VDC. This allows efficient brake operation without the need for higher voltage.

- Shorten brake intervention time: It is mentioned that the brake intervention time can be shortened by reducing the voltage to 103 VDC. This voltage level is still sufficient to securely hold the rotor disc, which contributes to efficient operation.

- 25% reduction of electricity: By using a lower brake coil voltage, a significant reduction in brake energy consumption is achieved, which is reduced to 25% compared to other brake systems.

- Reduced heating of the brakes: Reduced energy consumption results in reduced heating of the brakes. This improves brake durability and service life, as well as overall efficiency.
