| It may also increase efficiency of machines as there won't be frictional effects of brushes, commutators, etc, on the motor itself. |
|
| As the C3 milling spindle has no commutators, carbon brushes or ventilation parts, no further maintenance is required. |
|
| Direct current is produced by batteries, fuel cells, rectifiers, and generators with commutators. |
|
| Copper is also used for manufacturing commutators, welding electrodes, contacts, contact springs, high vacuum and other electronic devices. |
|
| The selection is rounded out by copper sections for starter commutators and for other auxiliary motors. |
|
| Losses also occur in commutation, mechanical commutators spark, and electronic commutators and also dissipate heat. |
|
| We produce hight quality commutators for varius applications from 4mm to 165mm outer diameter, including automotive, portable electrical machinery, electrical home appliances, aerospace, and armaments industry. |
|
| Applications range from electrical engineering to induction ovens, from the automotive industry and commutators for DC industrial or traction motors to household appliances industry such as microwave ovens. |
|
| Commutation system The commutators and brushes are made of high quality precious metal alloy and provide a minimized but constant contact resistance as well as insensibility to changes in environment. |
|
| Each year during the summer, the DC machines are shut down for an overhaul: servicing includes changing the carbon brushes and skimming the commutators, among other things. |
