FAQ
Well, we are Engineers, Machinists, Designers and Manufacturers first and Marketing guys second so we are working on it but we aren’t always that quick in that department. Have a good name? Drop us a line…
We designed the motor shaft grounding modules to be very easy to install. For shops that expect to install more than a few, we have a number of drill templates, spacers and extensions to help the installer deliver a professional looking product in less time and with less effort.
Aaki motor shaft grounding modules are designed, assembled and tested in Calgary, Alberta, CA
Aaki motor shaft grounding modules are not Ex rated.
We recommend on motors over 5 Hp that two units be installed where possible (one at each end of the motor on both shafts).
We build in a window that allows you to look at the amount of remaining brush life on the module. You don’t have to pull the brushes or remove any components to see the remaining brush life. We did this to ease the inspection process.
Depending upon the level of VFD eddy currents generated in the motor, these modules should last for the life of the motor. We recommend performing an inspection on the modules at least monthly for the first 6 months to determine a wear rate.
Unfortunately, there is no easy way to know or even measure if your electric motor system is generating eddy currents that can damage your bearings. It depends upon many factors such as motor condition, motor load, RPM, grounding conditions, etc. Some electric motor systems can operate for years without a problem and then a change is made to how the system operates or how other systems operate in the plant and the bearings begin to be eroded. The Aaki motor shaft grounding module offers one more level of protection against these costly premature motor failures.
No, some spools are mounted in shops, used for aircraft refueling, rail industry, coal hoppers in paint shops, well heads, anywhere they are pumping or moving any type of fluid that is non-conductive and the static generated can create a fire or explosion.
We have found that the majority of our customers prefer the 12 gauge stranded steel cable with yellow jacket. This cable works well with our 6” spool, providing a compact system for most static bonding applications. However some companies prefer to use a heavier gauge cable. For this purpose we also carry a 4 gauge high strand count copper cable with yellow jacket. This fits well on our 8” spool. The type of spool and gauge of cable would be determined by your company requirements. If you require help in choosing the right setup for your needs, drop us an email or give us a call. We would be happy to help.
We have never had one return in the 20 years we have been producing these. Depending upon normal wear and tear, we have sent out repair kits for handles, locking pins, cable and clamps, but the main spools body has turned out to be almost indestructible. Having said that, it’s still important to inspect, test and service them regularly as per your companies maintenance and testing program.
Takes 5-7 business days to process order once placed. After that standard shipping times apply.
Yes it is often put on brand new motors to preserve and maintain as well as used for repairs.
There is a 4” distance between flanges and the core is a 2” diameter
Aaki bonding spools are built to handle voltages and currents associated with static electricity. This means that the spool will handle high voltages and very low currents. Grounding applications typically require the device to handle generator voltages (120V to 600V) and currents that may be present during a fault condition (ranging from milliamps to tens or hundreds of amps).
The system design is often fundamentally different. For instance the clamp on a bonding spool is designed to pierce insulating material (such as paint or corrosion). The piercing point has a very small surface area and can’t handle a lot of current. Conversely, clamps for grounding applications often have a large surface area that contacts the grounding pole. This allows the clamp to transfer large currents without overheating.
Bonding is the act of electrically connecting two objects together so that the potential difference between them is close to zero volts.
Grounding is the act of electrically connecting an object to the earth, also known as earthing. Grounding also has the implication that significant currents may be involved, whereas bonding applies mainly to the conduction of very small currents.
