ZTP Series Auxiliary DC Motors for Railway Locomotives (Detailed Description) 

I. Overview of the ZTP Series Auxiliary DC Motors for Railway Locomotives
 1. The ZTP-series DC auxiliary motors are specifically designed for diesel and electric locomotives to drive hydraulic pumps, blowers, air compressors, auxiliary generators, tachogenerators, and other auxiliary mechanical equipment.
2. These motors comply with the General Technical Specifications for DC Auxiliary Motors Used on Railway Locomotives and EMUs (OXD.515.010-2001) or other dedicated technical specifications.   The motor is capable of withstanding shocks and vibrations generated during normal locomotive operation, and operates reliably under rain, snow, wind, and sand exposure. It is suitable for ambient temperatures ranging from −40 °C to  45 °C and altitudes up to 1200 m; for altitudes exceeding 1200 m up to 4000 m, refer to the relevant provisions in the technical specifications.

II. Model Designation of the ZTP Series Auxiliary DC Motors for Railway Locomotives
1. ZTP-62K: “Z” denotes DC motor; “T” denotes railway transportation; “P” denotes dedicated配套 motor; “62” denotes frame size; “K” denotes variant code.
2. ZBT—denotes a DC enclosed railway-dedicated motor.

III. Structural Types of the ZTP Series Auxiliary DC Motors for Railway Locomotives   Basic Mounting Configurations
 1. Horizontal mounting with feet on frame (IMB3), see Fig. 1: ZTP-1~5, 62K, 62K1, 62K2, 62G, 82B, ZBT-12.
 2. Horizontal mounting with feet on frame and flange on end shield (IMB35), see Fig. 2: ZTP-1~3, 12D, 22Z; Fig. 3: ZTP-63K; Fig. 4: ZTP-6 3K1; Fig. 5: ZTP-63D.
 3. Horizontal mounting with feet on frame and circular flanged end shield (IMB35), with terminal box located on top, see Fig. 6: ZTP-22B.
 4. Horizontal mounting without feet, with flange on frame (IMB10), see Fig. 7: ZTP-62A, 63A, 63B, 63B1, ZBT-63.
 5. Horizontal mounting without feet, with flange on frame (IMB10), see Fig. 8: ZTP-62A1.
 6. Vertical mounting without feet, shaft extension downward, with flange on frame (IMV10), see Fig. 8: ZTP-62L, 63L; Fig. 9: ZTP-61L.
 7. Other mounting configurations—including single-shaft or double-shaft versions—may be supplied upon user request. For single-shaft motors, a tachogenerator or other speed-sensing device may be mounted at the non-drive end.
 8. For IMB3 and IMB35 mounting configurations, the terminal box is positioned on the left side of the frame when viewed from the drive end (“standard box”). Upon user request, it may alternatively be placed on the right side (“reverse box”) or on the top of the frame. Motors with IMB10 or IMV10 mounting configurations do not feature a terminal box.
