Spring actuated and electromagnetically released disk brake type H2SPX powered by direct 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...

Normalized hole diameter ranges d - standard geared bushing hole diameters d smax - maximum geared bushing hole diameters d* smax - at extra charge it is possible to manufacture the brakes with the specially increased diameter of the gear hub ** -for the H2SPX112 and H2SPX132 brakes and for the geared bushing hole diameters from 32 to 35mm, the key groove with the width of 8 mm (the width of the groove is incompatible with PN/M-85005 and DIN 6885 standards) Hole diameter [mm]

Relevant brake applications with switching in the primary or secondary circuits are ensured by half- or full-wave rectifiers and fast electronic circuits. The manufacturer recommends to use as low alternating current voltages...

Rectifier B2-2P The B2-2P rectifiers series forms a complete full-wave rectifier unit for direct installation. The terminal strip provided facilitates installation and connection to the circuit. The rectifier allows feeding input voltage max. 400VAC, 2A which after rectification provides DC voltage of value equal to 0,9 input voltage. Rectifier B2-2P cooperates with brakes H2SPX63 + H2SPX200. For example Maximum input voltage (alternating voltage) - Uin = 230VAC, The resulting output voltage of the rectifier (direct voltage) - 0,9Uin= 0,9 x 230=207VDC Rectifiers dimensions B2-1P-600, B5-1P-600...

Circuit PS-1 is built on the basis of MOSFET type semiconductor technique which enabled achieving effects not available in traditional designs. The brake electromagnet energized through circuit of this construction enables the brake to achieve connection and disconnection time parameters analogous to breaking of circuit on direct current side. The parameters obtained are not however gained through utilization of additional electrical circuits and switches. Simplicity of installation and parameters achieved enable very wide application, particularly in cases requiring positioning of drives, operation with...

Having in mind the user who requires the control of the brake, we have designed special signaling and control circuits, which enable to control the state of the brake (engaged, disengaged) and the wear of the plate lining. The usage of these circuits enables to control the brake with the use of automatic elements, which ensure high level of safety and reliability. Due to its compact design, the microswitch can be used in any other applications, as long as its parameters meet design requirements. Response monitoring microswitch - KZ - control of the state of brake (engaged, disengaged), Microswitch...
