ZSN4 series DC motor is a specially developed for cement rotary kiln on the basis of Z4 series DC motor. by Simo technical team. This series of motors adopts octagonal structure, high stator space utilization, stator yoke laminated, and it can withstand the pulsating current and high current rate of change. The motor insulation class is F-class(150℃), so that the motor has a larger capacity. ZSN4 series motor can operate safely and reliably in harsh, dusty environments.
