- Rated shaft speed when the motor is loaded with an impeller, min-1 - 2600-2800
- Consumed current at the specified load and speed, A, no more than — 25
To drive the fans of the engine cooling system, two DC electric motors are installed with excitation from permanent magnets of domestic production.
Electric motors are switched on by the controller of the engine management system, fig. 7-37, via auxiliary relays and fuses singly or in pairs.
Pic. 7-37. Scheme of switching on the electric motors of the cooling system fans:
1 - right motor of the fan of the engine cooling system;
2 - additional relay;
3 - fuse;
4 - controller;
5 - additional resistor;
6 - relay for turning on the right electric motor;
7 - left electric motor of the fan of the engine cooling system;
8 - relay for turning on the left electric motor;
A - to the terminal «-» battery;
B - to the ignition relay;
C - to terminal «+» battery.
Electric motors are maintenance-free and should be replaced with new ones in case of failure.
