9.18. The electric motor of the fan of system of cooling of the engine Features of a design
Fans of system of cooling are resulted by two electric motors of a direct current with excitation from constant magnets. The controller of a control system of the engine operates work of fans. Electric motors of fans of system of cooling of the engine do not require service. In case of failure replace their new. For check of serviceability of electric motors take advantage of the data from tab. 9.6.
