Other salient points to be noted:
• The maximum transmissible torque is 2 times the specified nominal torque
• Keyway according to USAS B17.1-1967

Areas of Application:
• Housing Freewheels as automatic clutches in multi-motor drives fulfil here an important function
• They disengage a drive automatically as soon as it no longer provides power to the working machine
• The Housing Freewheels do not require any external operating equipment

Typical applications for multi-motor drives are:
• Generators
• Pumps
• Ventilators
• Fans
• Uninterrupted power supply

Application Example:
• Three Housing Freewheels are used in the multi-motor drive of a fresh air fan
• The fan is powered by either one or two electric motors, depending on the operating mode
• An auxiliary drive is provided to slowly rotate the fan during inspection or to ensure even cooling after shutdown
