The Bosch Rexroth Indramat MAC090A-0-ZD-4HC/110-A-1 from the MAC AC Servo Motors series is engineered for demanding industrial applications with a centering diameter of 110 mm and continuous torque of 3.7 Nm at 2000 RPM. This MAC090A servo motor incorporates tachofeedback and incremental/absolute encoder as its Motor Feedback, ensuring precise position control and smooth commutation. Rated for a Peak Pulse Current of 53 A, the motor operates on a modest 8.1 A constant current draw, delivering high dynamic performance. Its robust design accommodates ambient temperatures from 0 to +45 °C, making it suitable for both indoor and sheltered outdoor environments.
Featuring Natural Convection as its Cooling Type, the MAC090A-0-ZD-4HC/110-A-1 maintains thermal stability with a Thermal Time Constant of 45 min. The Protection Rating IP65 enclosure and Black prime coat (RAL 9005) housing coat resist dust, water ingress, diluted acids, oxidation, and chalking. Winding parameters include a Winding Inductance of 1.9 mH and a Winding Resistance of 1.85 Ω, optimizing current-to-torque conversion. With a Mass of 12.5 kg, this servo motor balances compactness and durability, while storage and transport temperatures ranging from –20 to +70 °C protect internal components.
An integrated Holding Brake provides holding torque of 6.5 Nm at a nominal voltage of 24 V, ensuring secure load retention. The brake assembly adds 0.5 kg to the motor mass and features clamping and release delays of 20 ms and 60 ms respectively. This model’s moment of inertia of 20 × 10⁻⁴ kg·m² and insulation class F complete its specification, delivering reliable performance in precision automation and motion control systems.
