Click to enlarge image(s) The frequency Drive System is for machine shops, home shops, or tool rooms with single phase power or for machines with 3-phase power on a 'step pulley' head that would like the convience of variable speed control. Using the VFD (Variable Frequency Drive) allows the operator to change spindle speeds by turning the speed dial and watching the readout display on the VFD box. The unit is sold as a kit with all parts required for mounting & connecting the unit to your motor. The kit includes the following: -Variable Frequency Drive Unit- See below to pick your unit -Mounting Box to hold the VFD -Mounting Arm for the system -All required electrical wires and connectors -Step-by-Step Installation Instructions -VFD Operators Manual -H&W Tool Free Support at 800-285-5271.

Each industry has it's own 'traditions' for mounting VFD's. MCC mounted VFD's are almost never seen in hospitals, labs, or universities. It is common in waste water plants to see VFD's mounted motor control centers. Space limitations and 'habits' are the common motivations. The issues that we see are several. One of the most common issues is the impact for the end-user regarding the life cycle cost and serviceability.

Small HP VFD's (20HP and less) are small enough that they fit into a standard MCC bucket. Larger VFD's are placed into custom buckets that do not have the tabs for the power connections and are direct cabled. I have an end user with a 100HP VFD (about 5 years old) with a failed main cooling fan. The entire MCC line-up had to be shut down for several hours because the fan was mounted on the back of the VFD heat sink that was flanged mounted. This meant that the drive was mounted (bucket was not removable) through a cut out and the fan was about 1/2' from the vertical bus bars. With the arc flash protective gear, the technician was not able to remove the small screws, etc.

Required to change the fan. Another end user was concerned that his VFD's only lasted 5-7 years before a catastrophic failure and had to be replaced. Gta san andreas indir. This was due to the inadequate cooling and dust build-up on the VFD heatsink. The VFD's needed to be completely removed from the MCC so proper access to the heatsink in order for it to be cleaned. A 10C rise over the VFD rated temperature typically will reduce the VFD's lifespan by 50%!
