H2S series - electromagnetic disc brakes - 2

Direct current brake series H2S characterizes relatively simple construction, facility for regulating brake parameters such as braking torque (reduction of springs), braking time (by way of appropriate electrical connection) 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 important when the equipment is operated by a number of drives operating additionally with high frequency of actuations. Brake parameters regarding time for...

H2S series - electromagnetic disc brakes - 3

ELECTRICAL EQUIPMENT A number of modules, ranging from simple circuits with classic designs, to complex assemblies ensuring quick action and drives positioning have been designed to drive the brakes. 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 as possible to supply the brakes. Appropriate choice of the control voltage will prevent or at least limit surges that may occur in power supply circuits. It is not...

H2S series - electromagnetic disc brakes - 4

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. 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 Disconnection of power supply on AC side The diagram...

H2S series - electromagnetic disc brakes - 5

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,...
