CNC Electric Motor – NSK Y4082
The Y4082 is a CNC machine tool electric motor (“CNC Electric Motor”) manufactured by NSK Ltd., designed for use as an axis or spindle actuator in machining centres and CNC machine tools. The motor interfaces with the dedicated drive/inverter of the control system, delivering the dynamic performance required by high-precision machining cycles. Refer to the machine documentation to confirm compatible revisions and variants.
The motor is the primary actuator of the axis or spindle: it converts electrical energy into mechanical torque and responds in real time to CNC commands for positioning, speed and acceleration. A motor failure causes immediate shutdown of the affected axis, resulting in total machine downtime and inability to complete the machining cycle; in continuous-production environments even a short stoppage incurs significant losses.
NSK Ltd. (Nihon Seiko Kabushiki Kaisha) is a Japanese manufacturer founded in 1916, Japan’s first ball bearing producer and today a world leader in precision bearings, linear technology and CNC machine tool components. NSK’s motion control division supplies high-precision motors and actuators to major OEM machine tool builders worldwide. Availability of the specific part number should be verified, as some series of NSK CNC motors may be legacy / discontinued.
