Balancing machine for electric armatures and hybrid rotors

2-plane measuring and balancing machine

Type EHK12

For the precise balancing of electric armatures and hybrid rotors in e-mobility, Hofmann offers flexible machine concepts that meet the high requirements for measuring accuracy with low unbalance tolerances and high speeds.

Depending on requirements, different machine concepts are available, from the manual 1-station machine, where measuring and balancing take place in one station, to the fully automatic 2-station machine, which enables measuring and balancing to take place separately in two stations. Depending on the rotor type, unbalance correction is carried out axially or radially by drilling or alternatively by riveting weights. The choice of stations and set-up depends on the cycle time and machine concept. All components can be individually combined to ensure maximum flexibility.

Loading can be done manually or automatically using robots or a loading gantry.

Special features

• Compact design
• Quick-opening service door with safety edge
• Unbalance measurement in 2 planes
• Stainless steel bearing pedestal for measuring the unbalance of magnetic components
• Mass balancing through manual riveting of weights
• Modular system designed for maximum flexibility
• Maximum ease of conversion
• Ideal accessibility (loading / unloading)
• Central access to media supply
• Basic equipment with a Siemens PLC and Siemens HMI
• Possibility of CAQ connection / master computer connection

Field of application

• Series production of electric armatures and hybrid rotors from hybrid car drives

Type EHK12-BBH2

For the precise balancing of electric armatures in e-mobility, Hofmann offers flexible machine concepts that meet the high requirements for measuring accuracy with low unbalance tolerances and high speeds.

Depending on requirements, different machine concepts are available, from the manual 1-station machine, where measuring and balancing take place in one station, to the fully automatic 2-station machine, which enables measuring and balancing to take place separately in two stations. Depending on the rotor type, unbalance correction is carried out axially or radially via drilling. The choice of stations and set-up depends on the cycle time and machine concept. All components can be combined individually to ensure maximum flexibility.

1-level measuring and balancing machine for hybrid rotors

Type EVW11-BM1

Various machine concepts are available for machining hybrid rotors. The fully automatic 1-station machine enables the unbalance to be measured and corrected directly in the same station. For higher production requirements, Hofmann also offers fully automatic 4-station machines. The decision on the number and design of the stations depends on the cycle time requirement and the selected machine concept.

Special features

• Compact design
• Unbalance measurement in 1 plane
• Mass compensation via axial drilling, alternative compensation variants (e.g. via circular milling on the outer diameter of the workpiece)
• Optionally with 90° angle drilling head for radial unbalance compensation
• V-Line modular system designed for maximum flexibility
• Automatic calibration device with TQC add-on software and SQL database
• Maximum ease of conversion
• Connection option for direct component labeling
• Optionally with DMC detection
• Ideal accessibility for loading/unloading (manual, automated via a robot or loading gantry, or in an interlinked line via an integrated round transfer)
• Central access to media supply
• Basic equipment with a Siemens PLC
• Possibility of CAQ connection / master computer connection
• Remote maintenance access

Field of application

• Series production of hybrid runners from passenger car e-drives

2-plane measuring and balancing machine for gear components of the E-axis

Type EVK11/II-BM1

A machine with maximum balancing accuracy has been developed for the machining of electric axis gears. Unbalance correction is carried out either via axial or radial drilling. Radial drilling is realized via a 90° angle drilling head, which is inserted into the spindle nose of the drilling spindle via the HSK interface.

Special features

• Compact design
• Unbalance measurement and correction in 1 or 2 planes
• Mass balancing via axial drilling
• Optionally with 90° angle drilling head for radial unbalance compensation
• V-Line modular system designed for maximum flexibility
• Maximum ease of conversion
• Connection option for direct component labeling
• Optionally with DMC detection
• Ideal accessibility for loading/unloading (manual, automated via a robot or loading gantry, or in an interlinked line via an integrated round transfer)
• Central access to media supply
• Basic equipment with a Siemens PLC
• Possibility of CAQ connection / master computer connection
• Remote maintenance access

Field of application

• Series production of gear components for the electric axle of electric car drives
