Product Description:

The MAF130C-0150-FQ-S0-BK0-05-V1 asynchronous motor is produced by Bosch Rexroth Indramat for the MAF IndraDyn Asynchronous Motors series. The unit functions as a rotary prime mover for industrial automation axes, delivering regulated mechanical power when paired with an IndraDrive inverter. By converting electrical energy to torque over a liquid-cooled stator, it supports positioning, conveying, and forming operations where high torque density and stable thermal behavior are required.

During locked-rotor conditions it can deliver a continuous torque of 150 Nm while drawing 54.7 A; this defines the thermal limit for holding loads without motion. The liquid jacket must circulate coolant at 3.3 l/min to remove the resultant copper and iron losses. When short load spikes occur, the shaft can withstand up to 330 Nm, giving the machine builder a margin for acceleration or shock loading beyond the continuous region. All heat generated in the windings and laminations that cannot be converted to mechanical work appears as 2.3 kW of power loss, and this value must be included in the cooling system’s heat balance so that winding insulation stays within class limits.

Under rated operating conditions the stator current drops slightly to 53.2 A, and the motor outputs 22.8 kW of mechanical power at a synchronous speed of 1500 rpm. At that point the shaft produces a working torque of 145 Nm, aligning electrical input with mechanical demand for continuous duty. The electromagnetic design yields a torque constant of 3.04 Nm/A at 20 °C, allowing the drive controller to predict torque from measured phase current without external sensors; this simplifies closed-loop regulation and improves dynamic response when the axis is commanded to ramp or reverse.
