Electrical hoist drive system |
摘要 |
The invention provides a hoist drive system for controlling the position of a hoist platform in a palletizer. In an embodiment of the invention, a hoist drive system comprises two electrical motors with dual output shafts. One motor has an encoder and as one motor rotates clockwise, the other motor rotates counter clockwise. A common shaft with a spring set safety break ties the motors together. The two motors are tied together electronically with a flux vector motor controller with input from the encoder. The flux vector motor controller controls the operation of the two motors, which drive two gearboxes, thereby enabling vertical displacement of a hoist platform coupled to the drive system.
