Обзор

The motors are asynchronous squirrel-cage motors with compact dimensions in an open fin-cooled design with self-cooling. The motors of the series 1LL8 are similar in construction to 1LA8 motors. IP23 degree of protection is achieved by opening the internal cooling circuit and supplying it with external cooling air.

These series of the 1LL8 motors are designed for direct connection to the three-phase supply.

Important preconditions: Motors of the 1LL8 type series are intended for installation indoors. They must not be subjected to humid, salty or corrosive atmospheres.

• Mains-fed operation
• Cooling method: IC01, self-ventilated
• Degree of protection: IP23
• Housing: Cast iron
