Product Description:
The B & R Automation's 8MSA4L.R0-V5 3-Phase Motor offers a rated torque of 5.6 Nm, ideal for repeat load handling in synchronized applications. With maximum demand, this synchronous motor offers a peak torque of 30 Nm, ideal for applications with rapid acceleration and deceleration cycles without compromising stability.
The 8MSA4L.R0-V5 motor contains five pole pairs that help in ensuring balanced magnetic field interaction between the stator and rotor. The construction of this motor supports a maximum rotational acceleration of 72289 rad/s² when the mechanical brake is disengaged. In terms of electric power, this 3-phase motor boasts a stator resistance of 1.45 Ω, determining opposition to current flow through the winding. In addition to this, the stator inductance of this synchronous motor is 9.2 mH, which is responsible for regulating current ripple and ensuring smooth electromagnetic torque. During locked rotor conditions, this motor has a stalled current of 6.98 A, which needs to be factored into correct drive sizing and overload protection. The environmental requirements of this motor involve a 65 °C maximum flange temperature to provide thermal performance well within safe working conditions over long-term usage.
The transportation of this motor is possible within a temperature range of -20 to +60 °C, with material integrity preserved through changing storage environments. During operation, this 3-phase motor bears relative humidity from 5% to 95%, non-condensing, to allow deployment in moisture-variable conditions without deteriorating insulation. The vibration compliance is according to IEC 60034-14 Grade R, which ensures that this motor is industrially reliable under operating stress. This synchronous motor qualifies for up to a maximum altitude of installation at 2000 meters to maintain performance under varying elevations. The 8MSA4L.R0-V5 motor weighs 7.7 kg to support secure mounting while ensuring mechanical compatibility with drive systems.
