STAI 1-8-45

STAI operators are robust commercial door operators with an overhead track. They offer the optimal operator solution for spring-balanced sectional doors with low lintel fittings or lack of lateral space for installation. Due to their robust design, they are equally suitable for use in underground garages. Gates with a maximum height of 4,500 mm can be automated. The gearmotors are based on the proven STA operators. All STAI series operators operate on the basis of an external control system. Special solutions for individual customer requirements can be implemented flexibly and quickly at any time.

STAI 1-8-45

Features:

  • Die-cast aluminum housing, rolled worm shaft and double worm shaft bearings
  • Emergency operation via unlocking mechanism on the guide carriage of the opener rail
  • Supply: 230/400 V/3~/50 Hz
  • Thermal protection in the motor winding
  • For gate systems with above-average switching operations, select an operator with increased motor duty cycle (HD).
  • Pluggable connectors
  • End position setting via electronic absolute encoder (AWG) or mechanical limit switches (MEC)
  • Version with external control, can be combined with extensive control program. Supply: 230/400 V/3~, frequency: 50/60 Hz, control voltage: 24 V-DC
  • When the output speed is increased (operation with frequency inverter), the output torque is reduced. In this case, the following applies: An increase of the output speed by 10 % causes a reduction of the output torque by 5 %.
  • Special designs such as further voltages and frequencies, output speeds and higher degrees of protection on request
  • Mounting and installation components available
  • For temperature ranges below -20 °C there is suitable oil and electric heating on request
