The R911224642 (MAC090B-0-PD-4-C-110-B-1-WI517LV) is an AC servo motor from the MAC Series, engineered for stationary operation under weatherproof conditions per EN 60721-3-3 and IEC 721-3-3 standards. It is suitable for dynamic applications such as press feeds and punching, especially when shock-damped mounted. The housing features a black prime coating resistant to diluted acids, bases, yellowing, and weathering, with an optional additional coating up to 40 mm thick. Mounting options include B5 or B14 designs in select models. This unit is specified without a blocking brake, uses a standard encoder mounting, and has the power connection on side B. In IM V3 and IM V19 positions, liquid accumulation at the output shaft must be avoided.
