This paper analyzes the sensitivity of the hoist system in crane applications from the three various control techniques of variable speed drives of induction
The "AC speed control motor unit" that uses the most popular single-phase capacitor-run induction motor, the small and highly efficient "Brushless DC motor unit
Conventional system uses slip ring induction motor for crane control. One of the methods is using microcontroller for speed control of three phase motor
It is to be emphasized that the rating of the motor with the connection of the 39% resist-or represents the rated hoisting speed at full load. The desirable
Today's Variable Frequency Controls and Flux Vector Motor Controls have become the industry standard for crane and hoist control. VFD's have replaced the older
HWR hoist control is recommended for use with DC series motors on AC powered cranes requiring the speed range, accuracy and dependability of a DC powered crane
Simply run unloaded hoist UP and the drive sets itself! Motor Requirements. Use with most standard “off the shelf” or vector a.c. 3-phase motors. Speed controls.
