1MB kit motors are maintenance-free asynchronous motors with high power density. Several motor sizes with different frame lengths and diameters are available for different performance requirements and installation conditions. The main spindles of modern CNC machines and complete machining centers are the main areas of application of these motors. Excellent smooth running and perfect servo quality for C-axis machining, thread cutting and spindle positioning characterize these kit motors. The asynchronous motor 1MB consists of the stator (1MS) and rotor (1MR).
