Excellent performance characteristics for compact machine class of machine tools



Spindle motors have a decisive influence on cutting productivity through their power and torque. In addition to suitable power, sufficient speed ranges must also be covered. Especially in the compact class, low complexity and ease of use play an important role in addition to price. The motor series SIMOTICS M-1PH3 is a spindle motor generation developed for universal implementation in plants and machines with motion control applications. The motors are provided in an asynchronous variant with forced ventilation and shaft heights of 100 mm and 132 mm. They are characterized by high robustness and simple application. The 2-fold overload capacitiy allows high cutting performance. The encoderless variant offers an attractive solution to put motors into operation quickly and easily. 1PH3 spindle motors were developed specifically for demands in turning and milling operations. They can be used in combination with SINUMERIK 828D control systems and SINAMICS S120 drivers. The motor series SIMOTICS M-1PH1 is your optimal choice for the entry-level of machine tools. The series can be combined with SINUMERIK 808 control systems and SINAMICS V70 drives.
