400Nm, 14rpm hand crank with mechanical limits
Sidone MIDI is a 3-phase motor with integrated safety brake. The worm gear makes the motor irreversible.
Typical applications are heavy rolling shutters, rolling grilles, vertical lift doors & sectional doors without spring compensation.
Mechanical limit switch: 2 Green cams for operating limits, 2 Red cams for safety limits, 2 Yellow cams for auxiliary controls.
OVERLOAD SAFETY FACTOR
Motor overload safety factor = 4 x the nominal motor amperage because the starting current of the motor can reach these levels for short periods.
MANUAL OPERATION
The manual override devices (hand crank or hand chain override) when power cuts-off, are based on a max strength of the end user of almost 40kg. In big or extremely heavy shutters the manual override is only intended in down direction.
HOLDING TORQUE
The drive unit can hold the weight of the door without slippage. The holding capability is the admissible load bearing of the worm gear construction.
