71918-140BLF applies advanced voltage regulation technology for its motor control, which provides reliable starting, smooth acceleration, fast deceleration, and increased torque capability. Thus, the application field mainly focuses on machinery and equipment needing low starting current, medium to heavy duty loads, and superior torque-to-standstill properties, such as conveyor systems, packaging machines, and printing machines. Other potential applications can also include electric doors, lifts, pumps, and ventilation systems.

The working principle of the 71918-140BLF is based on a three-phase asynchronous motor construction. This type of motor uses three phase power for the magnetization of its rotor. It generates magnetic fields on the stator that produces a rotating magnetic field, which interacts with the rotor\'s magnetic field, creating a mechanical force that drives the motor. The speed of the motor is determined by the frequency of the power supply, as well as the number of poles built into the rotor.

The star-delta connection can be used to start the motor without an excess current surge. In star-delta starter, the motor is started in the star mode, then switched to delta mode when the motor reaches its full operating speed. This type of connection is also referred to as Wye-Delta. It allows for a reduced voltage and current when starting the motor, which helps to protect the motor from over-current and over-voltage conditions. Additionally, this type of connection helps to improve the performance of the motor as it increases its efficiency and torque capabilities.

The 71918-140BLF is a reliable motor that provides superior performance under a variety of operating conditions. Its advanced technology and unique design provide excellent features and functions intended to support the needs of multiple application areas. Thus, it is especially suited for applications requiring low starting current, medium-to-heavy duty loads, and superior torque-to-standstill properties. It is also suitable for motor control and efficient operation in industrial machines, such as conveyor systems, packaging machines, electric doors, pumps, lifts, and ventilation systems.
