Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a Servotecnica part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These series from our supply network is the closest match on published figures.
Heavy-duty carbon-brush slip rings for very high current and voltage, with copper-graphite power rings and precious-metal signal rings. Large and heavy by design, but straightforward to maintain.
| Published maximum | SVTS A 05 | BHR Series Frameless Type (Carbon Brush) |
|---|---|---|
| Circuits | 3 | 76 meets or exceeds |
| Current per circuit | 20 A | 500 A meets or exceeds |
| Speed | 250 rpm | 10 rpm |
| Voltage | 240 V | 20,000 V meets or exceeds |
Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
