Product Description:
The 8MSA3S.EI-30 Three Phase Synchronous Motor features compact size, low weight and reliable performance. This motor ensures high dynamic torque at elevated speeds. It is highly efficient and delivers stable operation in demanding environments.
The 8MSA3S.EI-30 synchronous motor uses NdFeB permanent magnets for improved magnetic performance. It supports sinusoidal commutation using an EnDat encoder for precise feedback. The three phase winding utilizes a star connection that enhances operational efficiency. It features an IP64 protection class that is suitable for industrial environments with dust and moisture exposure. The torque constant is 0.99 Nm/A and the voltage constant is 60 V/1000 min⁻¹. The motor's stator resistance is 75 Ω and the stator inductance is 88 mH. Electrical time constant of the motor is 1.17 ms and the thermal time constant is 25 minutes. It does not include an integrated brake or fan system. The motor construction minimizes rotor inertia that ensures quick response times and excellent dynamic behavior. High overload capability of the motor allows peak torque generation when required. The motor’s low torque ripple reduces mechanical vibrations.
The B & R Automation 8MSA3S.EI-30 synchronous motor is designed to operate with a continuous current of 0.64 A under nominal load conditions. It can handle a peak current of up to 0.65 A during transient load increases or startup phases. The motor delivers a rated torque of 0.6 Nm for stable operation under continuous load. It is capable of producing a maximum torque of 0.7 Nm during short term overload situations. The motor operates at a rated speed of 3000 revolutions per minute (rpm). The 8MS series synchronous motor is powered by a supply voltage of 330 V which supports its rated operational characteristics.
