STA 1-12-19

Our STA 1 operator is the optimum solution for spring-balanced sectional doors. This is ensured by a gearbox specially developed for this application with a three-phase special motor that delivers a lot of power in the smallest space. The motor and gearbox of the STA 1 allow an extremely compact design, the housing is very narrow. The STA 1 series operators are available with a standard hollow shaft or a hollow gear shaft with multi-toothing to accommodate different shaft adapters..

* The values given were determined for an even distribution of the cycles. A cycle consists of two movements (opening and closing) and has a deflection of 10 revolutions of the output shaft in each direction. At ambient temperatures between 40°C and 60°C, a reduction of the maximum cycles per hour by 50% must be taken into account.

** For vertically moving doors and roller shutters, a reduction of the specified pull force by a further 20% may be necessary. Possible reasons for this are, for example, additional seals, double-walled profiles or an unfavorable winding ratio where the door height exceeds the door width. In addition, it should be noted that the maximum torque only occurs after one to two revolutions when thick or high profiles are used.

*** Alternative limit switch ratios are available upon request.
