Universal balancing machines series HM are conceived for highly precise balancing of a wide spectrum of rotors. They are suitable for balancing cylindrical rotors with integral shaft journals and for balancing disc shaped rotors on balancing arbors. Permanent calibration, ergonomic design and a logical operating sequence facilitate operation.

Series HM balancing machines usually require Class B or Class C enclosures. Safety class B should be chosen, if contact with the rotor or parts of the drive system may result in injury. Class C is to be used in cases, where the hazard of fragments detaching from the rotor cannot be ruled out entirely.
You can also choose from balancing machine, auto testing machine, and tensile testing machine. There are 3,731 motor balancing machines suppliers, mainly located in Asia. The top supplying country or region is China, which supply 100% of motor balancing machines respectively.
Larger machines over 25,000 lb. capacity will require customer supplied rotor with weights. Is an operator familiar with the balancing machine available to stop and start the machine, and to make sure all Safety Practices are observed? Is the balancing machine presently being used and in operating condition?
Although the API standards generally specify the rotor unbalance using U, API 617 has a minimum limit on eccentricity that is invoked for rotor speeds in excess of 25,000 RPM where the balance tolerance is limited at 250 μm or 10 μinch.
BR10 – Rotor balancing machine provides extremely high-quality balancing and covers virtually the entire spectrum of possible rotors of bigger hand tools, which can occur in repairs. Functionality, precision, safety at work, and low cost, are putting this machine in the top of the world supply.
The advantage of the pre-resonant balancing machines is that they can be balanced at relatively low rotor speeds (up to 400-500 rpm), which greatly simplifies the design of the machine and its foundation, as well as increases the productivity and safety of balancing.
Imbalance significantly reduces the operational safety of your machine. This is why balancing contributes both to a longer machine life and a higher personal safety of the operator. Elma Services has all the specialized knowledge, balancing equipment and service engineers to re-balance small, large, light and very heavy machine parts.
Soft-bearing balancing machines, like hard bearing machines, can balance most horizontally oriented rotors. However, balancing of an overhung rotor requires the use of a negative load hold-down attachment piece.
With soft-bearing balancing machines any imbalance will cause the rotor to move about as it spins. The machine measures the phase angle and amplitude of the movement and computes the unbalance which must be present to cause the motion. Appropriate corrections can then be made by the operator (Bloch & Singh, 2008).
Using an appropriate machine design and a suitable safety guarding machines can also be used for high-speed balancing Permanent calibration and rotor specific calibration Pedestals with integrated pins and V-blocks
A balancing machine is a measuring tool used for balancing rotating machine parts such as rotors for electric motors, fans, turbines, disc brakes, disc drives, propellers and pumps. The machine usually consists of two rigid pedestals, with suspension and bearings on top supporting a mounting platform. The unit under test is bolted to the ...
Fans, bladed rotors or tooling fall into this category and require contact protection, such as a safety fence around the machine. Opening of the protective equipment must be inhibited while the rotor is spinning. Class C If you cannot rule out the possibility that parts of the rotor may come loose and break away, then protection class C is required.

Reducing these vibration levels in the airframe to a minimum is absolutely essential in order to ensure the safety and longevity of the helicopter. ... The use of static rotor balancing devices is ...
A Balancing Machine is an instrument designed to measure and eliminate the imbalance mass of a rotor. In fact, Dynamic Balancing Machines spin the rotor to detect the center of mass through vibration sensors. These vibration sensors are usually accelerometers. Finally, simple calculations will indicate the position of the correction weights.
AUTOMATIC BALANCER. Automatic balancers manufactured by CIMAT can balance any type of rotor: disc-shaped rotors, for example, brake discs, clutches, pulleys and rotors with journals, for example, electric armatures, rotors of compressors etc.
Other Details: Machines model HDCM are belt driven horizontal type photo scanning Universal Hard Bearing Balancing Machine, provided with microprocessor based measuring panel HDCM – 8500 suitable for balancing different shapes of rotors, of electrical machines, Cylinders, fly wheel, rotor of centrifugal pumps and other type of rotating machines.
Balancing system composed of robot cell with two balancing machines, each one with unbalance measurement and correction function. The anthropomorphic robot loads and unloads the pieces from the client's pallet line on the balancing machines and can also load the master rotors from internal stores.
Balancing Machines for rotating parts. Balancing Machines are advanced technological solutions that allow to delete the rotating parts vibration of electrical, mechanical and electromechanical machines, improving their life and performances. Vibration and noise are usually caused by the unbalances present in the rotating parts.
Safety comes first. Because of job safety balancing machines must be equipped with protective devices. That is required by many national and international laws - as is in the countries of the EU. Following the EU rules a balancing machine can be CE labelled only, if it is operated with an appropriate protection.
Hofmann develops and manufactures horizontal, force-measuring universal balancing machines for the high-precision balancing of various rotors. Due to their modular design, they can be adjusted to fit various balancing requirements. Types: R-7.1, H-9.1, H-11.1, H-13 to H34
When the motor rotor is balanced, the safety operation rules of the dynamic balancing machine should be observed. 4. The stator of the rotor of the set motor must be placed stably and firmly, and it should be prevented from falling over.
We can provide you full range of spin test facility for all types of rotors asper the requirements and International standards.

Dec 10, 2012 · 1. Never remove or try to defeat machine safeguards. 2. Don't create new hazards, such as allowing objects to fall into the moving parts or by creating a new pinch point. 3. Report problems with machine safeguards to your supervisor immediately. 4. Never leave machines unattended with parts still moving. Remember that parts may still be moving after the machine has been turned off.
