Designed with simplicity, reliability, and ease of maintenance in mind, these motors offer superior technical and economic performance indicators, making them ideal for a wide range of applications. From small machine tools and medical equipment to electronic instruments and household appliances, the MS series motors are versatile and dependable. Additionally, they are compatible with RV series reducers, providing further utility in various mechanical systems. Notably, these motors boast a protection class of Class E and utilize the ICO141 cooling method, ensuring robust performance in demanding conditions.
Note: We offer bespoke motor solutions tailored to meet customers' unique requirements, ensuring every project gets the perfect motor.
Field conditions:
MS series motors are engineered to excel across diverse environments. They operate optimally within a temperature range of -20ºC to +40ºC and at altitudes up to 1000 meters, providing reliable performance under standard operating conditions.
Temperature rise and insulation:
Constructed with class F insulation (155ºC) and evaluated under class B insulation (80K), the MS series motors ensure prolonged service life and enhanced reliability, adhering to the highest industry standards.
Cooling and ventilation:
The MS series motors feature a totally enclosed self-fan cooling (TEFC) system, complete with an auxiliary flow plastic fan. This design complies with the IC411 provisions in IEC 60034-6, guaranteeing optimal cooling and ventilation.
Protection grade:
Boasting an IP55 protection grade, the MS series motors are well-suited for dusty and humid environments. For applications demanding higher protection levels, customized solutions are available to meet specific customer needs.
Motor protection:
To further safeguard the MS series motors, optional PTC, PT100, and other winding and bearing temperature measurement and protection devices can be integrated as per requirements, ensuring comprehensive motor protection.
Vibration:
The vibration speed of the MS series motors meets Grade A standards when operating under no load conditions. For specialized applications, Grade B motors are available upon request, accommodating a wider range of operational needs.
Voltage and frequency:
Our standard motors operate at 380 V/50 Hz, but we can engineer motors to function at any voltage between 200V and 660V for 50Hz applications. Moreover, these motors maintain excellent performance even when the power supply voltage deviates by up to 5% from the rated voltage.
Quality assurance:
Every stage, from product design to delivery, adheres to the ISO9001 quality certification system, strictly following rigorous quality procedures to ensure unparalleled product excellence.
