Переведите на русский язык и объясните, что такое постоянного тока моторы ты знаешь.
Translate into Russian and explain what types of dc. motors do ou know.
A 1. The magnetic system of DC machines comprises two poles. 2. These poles are stationary in space. 3. They create a magnetic flux of constant magnitude. 4. Between these poles an armature is in¬serted. 5. To rectify the current in the external circuit the machine is furnished with a special device called the commutator.
В 1 There are three types of dc motors: the series motors, the shunt motors, & the compound mo¬tors. 2. These types are alike externally. 3. They differ in construction of the field coils.4. They differ in the connection between the field & the armature.
С 1. The dc shunt motor contains a field composed of many turns of wire. 2. Its field is connected in parallel with the armature. 3 The motor has constant-speed characteristic. 4 It is used on applications that require constant speed.
