The motor adopts F-class insulation structure, so that the motor has a larger capacity. According to the special working conditions of the cement rotary kiln, the design and manufacture of the motor can be carried out according to the requirement that the starting torque of the motor can reach 2.5 times the rated torque. The use of cooling allows the motor to operate safely and reliably in harsh, dusty environments.
The rated voltage of the motor armature is 440V. It can also derive 400V, 220V or other voltage according to the user’s requirements.The low armature voltage is a constant torque speed regulation. Under the condition of continuous armature current, the minimum motor speed can reach 20r/mm. At this time, the rated torque can still be maintained, and the rotation speed is stable.
The rated excitation voltage of the motor is 180V, other excitation voltages can also be derived.
