MAC041A-0-FS-4-E/050-A-0/WI651LV
MAC AC Servo Motors
The Bosch Rexroth Indramat MAC041A-0-FS-4-E/050-A-0/WI651LV servo motor is a precision drive unit within the MAC AC Servo Motors series, engineered for demanding industrial automation applications. Key features include a Centering Diameter of 50 mm for precise shaft alignment and a Cooling Type of Natural Convection that ensures efficient thermal management without auxiliary fans. Equipped with an Encoder Type supporting either Incremental or Absolute feedback, this motor delivers the accurate positional control required for high-performance motion systems.
This model features a rugged primer-coated black housing for corrosion protection, with coating thickness not exceeding 40 millimeters, maintaining a low thermal time constant for rapid temperature stabilization. The motor offers a Protection Rating of IP65, safeguarding against dust ingress and water jets, and an Insulation Class of F to withstand elevated winding temperatures. Designed for operation in environments up to 95% relative humidity, the unit integrates thermal switches within the windings and stator housing to prevent overheating and ensure continuous reliable performance.
Additional specifications include a storage temperature range from -20°C to +80°C and an operating ambient range from 0°C to +45°C, with a maximum humidity tolerance of 95%. Power connections are located on the housing side labeled A, and the motor provides Tachofeedback for stable speed control. The absence of a holding brake reduces inertia and simplifies system integration. Built for stationary operation, the MAC041A-0-FS-4-E/050-A-0/WI651LV delivers high constant torque at standstill with minimal continuous current. Its compliance with international protection and insulation standards, combined with its durable construction, ensures exceptional efficiency and long-term reliability in industrial environments.
