The motors are manufactured for voltage 6000 V.
Degree of protection– IP23.
The motors are cooled by self-ventilation.
The motors are produced with frictionless bearings, with one shaft end. Terminals are brought to the terminal box. The terminal box has a bursting disk and meets modern requirements to short-circuit current resistance.
Winding insulation is thermosetting, type “Monolith-2”.
The motor designation is decoded as follows:
А – asynchronous
ХХХХ – Power, kW
Х – Voltage in kV, other than 6 kV
ХХ – Number of poles
ХХХ – Climatic construction and allocation category
|Type of the motor||Power, kW||Rotational speed, rpm||Eff., %||cos φ||Mmax/Mnom||Mstart/Mnom||Istart/Inom|
