Product Description:

The MAC025A-0-WS-4-E/040-A-1/WI671LV is a high performance motor manufactured by Bosch Rexroth and tailored for industrial automation tasks. It delivers outstanding reliability and precise motion control. The power plug is mounted on side B which allows straightforward wiring and seamless system integration.

The MAC025A-0-WS-4-E/040-A-1/WI671LV servo motor operates with a rated speed of 10000 min⁻¹ for fast and responsive motion control. It delivers a continuous torque of 0.27 Nm under normal working conditions. The servo motor has continuous current at standstill is 1.26 A which ensures constant performance without overload Its torque constant is rated at 0.22 Nm per ampere which ensures efficient and stable torque generation. The servo motor rotor moment of inertia is 0.23 x 10⁻⁴ kgm² which enables swift acceleration in dynamic operations. It has a tacho voltage output of 3 V per 1000 min⁻¹ ensures accurate speed monitoring and control. The tacho constant is rated at 0.75 V per 1000 min⁻¹ for accurate feedback response The MAC025A-0-WS-4-E/040-A-1/WI671LV servo motor supports cooling through natural convection or surface contact which depends on the mounting configuration. It features an incremental encoder for position feedback which comes with a standard mounting interface. The servo motor is built without a blocking brake to simplify design and reduce weight. The servo motor insulation system of this model is rated Class F for thermal endurance in industrial settings. It operates safely in ambient temperatures between 0°C and 45°C and supports storage conditions from -20°C to 80°C.

The MAC025A-0-WS-4-E/040-A-1/WI671LV servo motor has a minimum bending radius of 40 mm for fixed cable routing. It enables secure and compact installation in limited spaces without cable stress. The servo motor enclosure ensures a minimum protection rating of IP65 which provide resistance against dust and low pressure water.
