Product Description

The MAC093A-0-LS-4-C/110-A-1/WA610XX is a Rexroth manufactured AC servo motor variant that offers reliability and zero maintenance. It has the International Protection 65 that enables the motor to be used directly within the working area of the machine even under poor environmental conditions such as the effects of coolants, soluble oil emulsions, etc. The winding inductance and resistance of the motor are 4 mH and 0.328 ohms respectively. The thermal time constant is 50 mins and the type of cooling to cool down the motor's internal temperature is natural convection.

The usable motor speed is determined by the drive used and this machine has a rated speed of 4000 rpm. The MAC093A-0-LS-4-C/110-A-1/WA610XX has a standard holding brake of 6.5 Nm. The nominal voltage of the holding brake is 24 V with a precision of 10 percent. The nominal current corresponds to 0.7 A at the standard holding brake. The release and clamp delay are 60 ms and 20 ms respectively. The weight of the machine is 13.6 kg where 0.6 is contributed by holding the brake. The continuous torque value of the motor at a standstill is 9.2 Nm whereas the continuous current value of the motor at a standstill is 22 A.

Mounting the motor to the machine is simple. Pinions and belt pulleys can be directly mounted onto the shaft because the design of the bearing assembly makes the application of high radial loads possible. The housing is coated by black paint (RAL 9005), and the length of the motor type MAC 093A is 275 mm. The power is extracted at side A, and there are thermo switches built into the windings of the motor and the stator housing. It has the built-in tacho feedback incremental encoder with standard mounting. There is a 12-pin flanged socket on the motor for the feedback and encoder connections.
