2HZg series - electromagnetic disc brakes

Product catalog summary

Overview: The document details the specifications and features of the 2HZg series electromagnetic disc brakes, designed for constant braking torque and powered by alternating current. These brakes are used for braking rotating machine parts and ensuring precision positioning, functioning as safety brakes with high repeatability.

Specifications: The brakes are spring-actuated and electromagnetically released, characterized by simple construction and adjustable parameters such as braking torque and time. They operate quietly, which is beneficial for equipment with high actuation frequency. The brakes are available in various configurations to suit different climatic conditions and supply voltages (3x230, 3x400, 3x500, 3x690V).

Functionality: The brakes are designed for emergency stopping, immobilizing machine actuators, and minimizing drive run-on times to meet safety requirements. They can be integrated with electric motors to create self-braking motors, enhancing safety and positioning capabilities.

Technical Parameters: The document provides detailed technical parameters for different brake types (2H(Z,Y)g 90, 100, 112, 132, 160), including supply voltage, power, braking torque, maximum speed, weight, and operating temperature range. The operating times for releasing and braking are also specified, though they may vary based on installation and environmental conditions.

Design and Dimensions: Detailed dimensions and mechanical sizes are provided for each brake type, along with options for mounting flanges, manual release levers, and releasing screws. Protection ratings range from IP44 to IP56, depending on the sealing and cover options.

Customization and Standards: The manufacturer reserves the right to modify the product for development purposes and offers the possibility of special versions. The brakes comply with various climatic standards, such as MT and TH.

2HZg series - electromagnetic disc brakes-2

Spring actuated and electromagnetically released disk brake type 2HZg powered by alternating current. Designed for braking rotating machine parts and their precision positioning. Utilized as safety brake. High repeatability even with large number of actuations. The brake characterizes relatively simple construction, facility for regulating brake parameters such as braking torque, braking time and also possibility of supply from alternating current source after connecting up a rectifier circuit delivered at customer's request along with the brake. An additional feature is quiet operation, particularly...
