When it comes to expanding the longevity of your motor bearings, it’s hard to beat CoolBLUE inductive absorbers. These reliable devices limit the high frequency current from the VFD output, diminishing the damage to your machine.
Unlike other solutions, CoolBLUE inductive absorbers minimize the effects of electrical discharge machining without deteriorating over time. From their simple installation to their no-maintenance guarantee, they’re one of the easiest and most effective ways of protecting your motors. Read on to discover how the installation process works, what to expect during the fitting experience, and the capabilities of CoolBLUE technology.
Step 1: Preparing for Installation
Perhaps most importantly of all, CoolBLUE absorbers can normally be quickly and easily installed with minimum downtime and regular maintenance costs. Installation takes minutes, which means that your process can be up and running again in no time.
Although the installation of CoolBLUE cores is simple and fast, it’s still important to take the appropriate measures to ensure that workplace personnel remain safe. As such, all staff should follow workplace safety procedures regarding motor diagnosis, electrical testing, and repair practices. Make sure that employees involved in the CoolBLUE installation process wear proper PPE.
Step 2: Fitting the CoolBLUE Cores
CoolBLUE inductive absorbers fit around the power cables running between the motor and the VFD. From this position, the unique composition of the cores allows them to choke the unwanted high frequency currents generated by the VFD, protecting the motor bearings from damage. When installed correctly, the CoolBLUE inductive absorbers can reduce overvoltage peaks, noise, EMI currents, and motor bearing currents.
To install CoolBLUE cores correctly, three power phases need to move through the center of the core. Do not include shielding or grounding wire. In the case of multiple conductors, it’s recommended that all power conducting wires are passed through the core, while excluding the grounding and shielding wires.
NaLA cores are placed over each phase conductor. The NaLA Cores are installed towards the mot or, the CoolBLUE cores are installed towards the VFD. Please see the Installation Instruction sheet.
Step 3: Mounting the CoolBLUE Cores
The weight and size of CoolBLUE cores may sometimes require a mount and clamp to secure the cores to the drive wall, or another suitable location. Mounting is not mandatory, but may be advised depending on the circumstances of your installation. If the core in question is heavy, the mounting process can provide additional support, and specially-designed brackets are available.
There are a range of bracket sizes available that suit all CoolBLUE cores. Ideally, experts should evaluate the machine prior to installation to determine whether mounting is necessary. This will help save time during the installation process, as any required mounting equipment will have already been purchased.
While using mounting equipment, make sure that no metal besides the power cables interferes with the center of the cores, as this can negate the unique CoolBLUE absorption effects.
Step 4: Using the CoolBLUE Installation Kit
The CoolBLUE kit that you purchase for your electrical motor should include the correct number and size of CoolBLUE cores according to your system. The kit will come with instructions that you can follow for a safe and easy installation. Remember to perform Lockout/Tagout procedures before beginning work for health and safety purposes.
The Capabilities of CoolBLUE Inductive Absorbers
Featuring a range of core sizes to fit a variation of motor applications, CoolBLUE inductive absorbers are the ideal solution for cost-effective motor longevity. With their quick and easy installation, CoolBLUE absorbers can boost efficiency, productivity, and even safety in the workplace, with very little effort and maintenance expense.
