Electric tools & Elevator dynamic balance scheme

1.Angle grinder motor shaft (including commutator)

The rotor of the Angle grinder belongs to the structure with commutator winding, with a rotational speed of 10,000-30,000 r/min. It is recommended to use the special serial-excited balancing machine type for more stable measurement results.Fuman Machinery Serial rotor balancing machineSpecialized adaptation.

2.Electric drill/impact drill rotor

The rotor speed of electric drills and impact drills is 800-3000 r/min, with high requirements for rotational accuracy. It is recommended to use G2.Grade 5: The commutator is finely balanced separately after assembly.

3.Hair dryer/curling iron high-speed motor

The high-speed motor for hair dryers and curling irons is 100,000 + r/min, which belongs to high-speed brushless motors.Fuman Machinery Laser machine balancing Machine & Cover precise unbalance correction.

4.Garden tools (lawn mowers/trimmers)

The motor speed of the lawn mower and trimmer for garden tools is 6000-12000 r/min. The working environment is dusty and vibrates greatly.It is recommended to achieve double-sided balance +automatic unbalance correction and file the data by piece.

5.Electric wrench/electric screwdriver rotor

Electric wrenches and electric screwdrivers rotor are industrial-grade electric tools with a rotational speed of 1000-3000 r/min.

6.Elevator traction wheel/traction wheel

Elevator traction wheels belong to large-diameter disc-type parts, with diameters ranging from 400 to 800 mm.It is recommended to use vertical single-sided balancing and dedicated fixtures, and file the data by piece.Regular rebalancing is required as stipulated in TSG T7001.

7.Electric engraving machine /PCB drilling machine electric spindle

The spindle speed of electric engraving machines and PCB drilling machines is 30,000 to 80,000 r/min, which belongs to the precision grinding level.It is recommended to use precision soft supports.

8.Micro and small motors (axial flow fan armature)

Micro and small motors (including axial flow fan armatures) belong to the small components in the category of power tools, with large mass production scales and tight production cycle requirements.
