Electric motor ME-255 – a direct current with excitation from constant magnets.
At inclusion in a feed circuit of the electric motor of the additional resistor 6 shaft of an anchor rotates with the reduced frequency. The resistor fastens two spring washers in a casing of the fan of a heater. Size of resistance of the resistor – 1,5 Ohm at 20 ° With.
It is recommended to replace the faulty electric motor, as a rule, new. The unique repair – зачистка a collector.
| PERFORMANCE ORDER |
| 1. To turn away screws of fastening of a cover 6 (fig. of the Detail of the electric motor of a heater of a heater see) and to remove it. |
| 2. Then to remove from an anchor shaft a lock washer 1 and to take out an anchor 4 of the case. |
| 3. Assemblage is made upside-down. |
| 4. Check of a technical condition is similar described for the electric motor of a cleaner of a windscreen (subsection 11.4.1.2 see). |
