Replacement Motors

Direct Replacement A GE DC motor with a model number which has the format , 5CDNNNLLNNNLNNN, 5CDNNNLLLNNLNNN or 5BYNNNLLNNNLNNN (where N=number and L=letter) will be replaced with an exact electrical/mechanical replacement of the original motor. The new motor will be supplied with the up-to-date versions of the accessories. Non-Direct Replacement To replace a motor which has different mounting dimensions than the Kinamatic motors shown in this publication (e.g., a motor made by a different manufacturer or an older GE motor), three options exist . When replacing a motor made by a different manufacturer, all of the information listed on the SAM-QC form (pages 1.10 and 1.11) is required for quoting and manufacturing. When replacing an older GE motor, the model and serial number of the original motor are required for quoting and manufacturing a replacement . 1. Standard Replacement The new motor will be our standard offering (Kinamatic motor shown in this publication) which duplicated the older motor’s basic rating (horsepower, armature volts, field volts, and field winding type). The new motor will not duplicate the older motor’s winding characteristics (e.g., resistance, inductance, amperage, or regulation). The new motor will not duplicate the older motor’s drive end shaft dimensions or frame dimensions. The new motor will not duplicate the older motor’s armature inertia, overall frame height , or overall frame length. Standard Class F rise, 1.0 service factor, and NEMA standard overloads (as defined in the Accessories and Modifications section, page 3.17 item 20) will apply unless otherwise specified. The new motor will be supplied with up-to-date versions of the accessories of the older motor. Pricing: Use standard pricing given in this publication. 2. Mechanically Interchangeable Replacement (Up-to-date replacement) This option is available if, and only if, the shaft height of the older motor is reasonably higher (varies with motor size, but typically greater than 1 inch is sufficient) than the shaft height of the Kinamatic motor at the same rating. The new motor will be our standard offering (Kinamatic motor shown in this publication) which duplicates the older motor’s basic rating (horsepower, armature volts, field volts, and field winding type). By special machining the drive end shaft ,

the new motor will duplicate the older motor’s mounting dimensions. (C & FC dimensions may vary from original). The new motor will not duplicate the older motor’s winding characteristics (e.g., resistance, inductance, amperage, or regulation). The new motor will not duplicate the older motor’s armature inertia, overall frame height , or overall frame length. Standard Class F rise, 1.0 service factor, and NEMA standard overloads (as defined in the Accessories and Modifications section, page 3.17, item 20) will apply unless otherwise specified. The new motor will be supplied with the up-to-date versions of the accessories of the older motor. Pricing: Use standard pricing given in this publication, plus add for special shaft dimensions (page 3.19, item 24) and a transition base (page 3.3, item 6). 3. Dimensional Duplicate (Obsolete duplicate) This option applies only to older GE motors and is only required when a mechanically interchangeable replacement motor is not applicable (e.g., shaft height difference does not allow for a transition base, or motor is coupled at both ends and a dimensional duplicate of the frame is required). the new motor will duplicate the older motor’s basic rating (horsepower, armature volts, field volts, and field winding type). The new motor will duplicate critical dimensions of the older motor’s frame and shaft(s). the new motor will be updated with current electrical features, will not necessarily duplicate the older motor’s winding characteristics (e.g., resistance, inductance, amperage, or regulation). Standard Class F rise, 1.0 service factor, and NEMA standard overloads (as defined on page 3.17, item 20) will not apply unless otherwise specified. The new motor will be supplied with the up-to-date versions of the accessories of the older motor. Pricing: Refer to Wolong for producibility and pricing.
