Product Description

The MAC093A-0-LS-4-C/110-A-1/WA611XX/S001 is a zero maintenance remarkable MAC servo motor created by Indramat Rexroth. The motor is extensively used in industry for precision control and is well known due to its permanent magnet-excitation. This motor has a motor frame of 093 and length A. The motor feedback is tacho with incremental encoder. The mounting style of the MAC093A-0-LS-4-C/110-A-1/WA611XX/S001 is standard. The tacho voltage is set to the nominal motor speed. As this variant has more than 3000 rpm, the supply voltage is 3V per 1000 rpm.

The torque constant of the MAC093A-0-LS-4-C/110-A-1/WA611XX/S001 at 20 C is 0.438 Nm/A. This variant has standard holding brakes at 6.5 Nm. The working principle of the holding brake is based on the closed-circuit principle. At zero current, a magnetic force acts on the brake armature disc. To open the holding brake, 24 V DC is applied which cancels the permanent magnetic field. The type of winding is LS, and the rated speed of this MAC servo motor is 4,000 revolutions per minute.

The thermal time constant of the motor is 50 minutes which means it will take 50 minutes to reach 63% of its steady-state temperature.?For storage and transport, manufacturers advise to maintain a temperature range between -20 C to 80 C. The datasheet of the motor indicates that the motor can be best installed under 1000 m sea level height and temperature range between 0 C to 45 C. The motor has class F insulation installed in it for protection and durability. The rotor moment of inertia of MAC093A-0-LS-4-C/110-A-1/WA611XX/S001 without holding brake is 22 x 10-4 kgm2, and it increases to 23.06 x 10-4 kgm2 with holding brake. The total mass of the motor is 13.6 kg, and it has a protection category of 65.
