    Portable Field Balancer

    Portable field balancing tool with touch screen for single-plane and two-plane rotor balancing at rotation speed up to 6000r/min

    Portable field balancer with a touch-screen interface supports single- and two-plane correction. Compared with conventional field balancers compact and easy to carry, and no external drive is required. Measurements are taken on the installed rotor while running. Using the influence-coefficient method for calibration, the software calculates the correction mass and angle and guides add/remove weighting. Only a speed input and two vibration inputs are needed; connections are simple and there are effectively no space constraints.

    Applications

    Portable field balancers are commonly used for on-site dynamic balancing of fan rotors, motor rotors, and crushers. They are also suitable for direct balancing checks on installed motors.

    Balancing machines are instruments that indicate if a rotating component, such as a rotor or fan, rotates in an unbalanced manner. If the component wobbles or vibrates a lot, the balancing machine will point out the imbalance so it can be corrected. The importance of balancing is directly related to the longevity of the rotating component and how well the component functions.

    Soft-bearing machines use flexible supports, making them sensitive to very small vibrations and suitable for lighter or smaller parts that require high accuracy. Hard-bearing balancing machines, on the other hand, use more rigid supports, so they are more suitable for larger and heavier rotors. Hard bearing balancing equipment may be less sensitive to tiny vibrations, but they are easier to set up and give reliable results across a wider range of workpieces.

    Balancing machines are used to rotating parts such as motor rotors, impellers, fans, flywheels, clutches, gears, pulleys, and brake drums. By correcting unbalance, they help reduce vibration, extend service life, and keep production running more smoothly.

    Balancing machines can be configured with belt drive, universal joint drive, or self-drive. Belt drive is usually chosen for smaller rotors that require accuracy, while universal joint drive delivers higher torque and is safer for heavier parts. Self-drive designs are used when the workpiece can rotate under its own power.

    Accuracy may be affected by operator handling, incorrect markings, or mismatched correction points. Technical issues such as damaged sensors, loose connections, or electronic failures can also play a role. Regular calibration and proper setup help keep results consistent.
