Product Description:

The MAC093A-0-LS-2-C/130-A-3 is produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Tailored for analog drive systems, the unit converts current-regulated commands into precise rotary motion for positioning tables, feeders, and similar automation axes. A built-in tachogenerator supplies real-time speed data so analog controllers can close the velocity loop without auxiliary encoders. This arrangement supports applications that still use established servo platforms and need direct speed feedback from the motor.

The motor has a nominal speed of 4000 rpm, giving the axis ample headroom for rapid jogging while remaining within continuous-duty limits. The winding code LS indicates the coil resistance and inductance used with legacy current amplifiers, helping maintain stable commutation at high slew rates. An internal brake delivers 22 Nm of static holding torque to secure vertical or high-inertia loads during power-off states. Thermal energy is removed by natural convection, so no external blower or liquid circuit is required in most cabinets. Precise mechanical alignment is provided by a 130 mm centering diameter, allowing rigid mounting on gearbox flanges or adapter plates without shims.

The brake is an extra heavy-duty blocking brake, which supports frequent stop-and-hold cycles common in indexing machinery. The tachogenerator outputs 1.5 V per 1000 rpm, a level compatible with conventional analog velocity monitors. Power conductors reach the stator through a connector on side A, which can simplify cable routing when the motor is installed against upright machine frames. With a frame designation of 093 and a housing length coded as A, the motor occupies moderate space while leaving room for adjacent couplings and mounting hardware. Standard speed feedback quality is used for the tachogenerator signal during closed-loop operation.
