Siemens drives and drive parts

A failed drive stops a machine just as surely as a failed motor, and for older Siemens drives a new replacement is often no longer available. GWS Parts has 228 different Siemens drive parts in stock, 964 pieces in total, from complete units to boards, modules and power parts, each listed with its full Siemens order number. SIMOVERT MASTERDRIVES (6SE70) is no longer produced, but many machines still run on it. We stock MASTERDRIVES control and option boards (6SE7090) as well as power sections and other parts, which are often the quickest way to get a machine running again without replacing the whole drive system. For newer installations we have SINAMICS parts, including S120 motor modules and line modules and G120 control units and power modules. We also carry MICROMASTER 4 frequency inverters, since replaced by SINAMICS G120, and SIMOREG DC drives for machines with DC motors. Matching Siemens motors are on our motors page. When you look for a replacement, compare the complete order number on the type plate, including the version or hardware revision where it is given. For boards and modules, the firmware or hardware version can matter for compatibility with the rest of the drive. If you are not sure, send us a photo of the type plate and we will check it for you. The condition of each part is stated on its product page: new, used or reconditioned. Can't find the part you need? Send us the order number.
