Product Description
The MAC115A-0-FS-3-C/130-A-2/S022 from Rexroth is a 3000 rpm AC servo motor that has a nominal rotational torque rating of 28 Nm at standstill operating mode at 20 degrees Celsius temperature. At standstill operating mode, the MAC115A-0-FS-3-C/130-A-2/S022 servo motor draws 32.5 amperes of current and requires 240 to 480 volts AC to operate with a 3-phase input voltage configuration and an input voltage frequency of 50 to 60 Hz.
This servo motor has a low rotor moment of inertia of 123 x 10⁻⁴ Kg·m² that allows this motor to quickly accelerate and decelerate its speed without taking a longer starting time, hence making it quick to respond to speed regulation. With a torque constant of 0.588 Nm per ampere, the motor offers an efficient design that makes this motor perfect for high-power industrial applications. The copper coil winding on this servo motor has a low winding resistance of 0.076 ohms, keeping the power losses at a minimum and helping keep the overall design of the motor efficient. The thermal time constant of this motor is 90 minutes, which is the time it takes for the motor to reach 63% of the nominal ambient temperature this motor operates on.
This servo motor does not feature an encoder but does come with a tacho feedback speed regulation system and does feature a second shaft end in order to attach an external encoder. The tacho voltage rating for this motor is 3 volts for every 1000 rotations per minute of speed this motor attains. The motor also comes with a 60 Nm heavy-duty shaft-blocking brake that requires 24 volts DC to operate with a nominal current rating of 1.5 Amperes.
