Product Description

The B2.SM.503-44B0 motor is an exceptionally efficient and robust device developed for a variety of uses. It functions at a standard 330 Volts voltage and provides a steady torque that equals 1.75Nm.

The B2.SM.503-44B0 servo motor speed can reach up to 4000 Rmin⁻¹. It provides excellent performance for challenging tasks. It requires 2.1 Amperes standard current for operating and guarantees efficient energy use while upholding dependability. This B2.SM synchronous motor has been made for systems functioning at 200Hz frequency. It delivers accurate and consistent performance. With a power consumption of 0.73kW, it is ideal for operations that demand moderate energy levels. The motor is safeguarded with an IP65 rating, which prevents dust and water from entering, thus promoting its longevity in challenging conditions. The 503-44B0 SM Motor is equipped with a WED: 180-2 winding type, enhancing its effectiveness and dependability. A PTC thermistor is included, that protects the winding from heating up to 140°C temperature. This guarantees protection and avoids excessive heat during extended or intensive tasks. The motor meets the flange accuracy requirements of grade N which is in line with DIN 42955 standards. The 44B0 synchronous motor contains a braking system that operates at 24V and draws a current of 0.58A. This brake provides a 4.5Nm value of torque that exhibits strong stopping capability for accurate motion management. This set of specifications renders it perfect for uses that demand regulated and safe cessation of activities. 

The weight of this type B2.SM.503-44B0 motor is 3.30 kg. This design is easy to handle and install due to its light weight. The engine is small but strong that is complying with industry standards for dependable and effective equipment. The SM Motor delivers accurate performance, energy-saving features and robust build quality. All these features positioned it as a flexible option for industrial uses.
