Data for verification
| Shaft rotation speed when the electric motor is loaded with an impeller at a voltage of 12 V and a temperature of (25±10)°C, min⁻¹ | 3000 ±150 |
| Current consumption at the specified load and rotation speed, no more than, A | 4,5 |
| Low speed of rotation of the anchor shaft with impeller, min⁻¹ | 2200 ±150 |
| Current consumption at anchor rotation frequency of 2200 min⁻¹, no more than, A | 2,7 |
Electric motor ME-255 direct current with excitation from permanent magnets. The electric motor connection diagram is given in subsection 12.7.
When additional resistor 3 is connected to the electric motor power supply circuit, the armature shaft rotates at a reduced frequency. The resistor is secured with two spring washers in the heater fan casing. The resistor resistance value is 1.5 Ohm at 200°C.
A faulty electric motor is usually recommended to be replaced. The only possible repair is cleaning the collector.
1. To disassemble the electric motor, it is necessary to unscrew the screws securing the cover 6 (see fig. Heater motor parts) and take it off.
2. Then, remove the lock washer 1 from the armature shaft and remove the armature 4 from the housing.
3. Assembly is carried out in reverse order.
