Product Details

Brief Introduction

Engineered for precision DC energy conversion, this system optimizes electromechanical transfer through synchronized armature winding and commutation dynamics.

 

Bidirectional Energy Transfer: Enables seamless motoring/generating transitions by managing counter-EMF during ZTP-180D locomotive starter motor voltage application or mechanical drive input.

Mica-Insulated Segments: High-purity copper commutator bars isolated with thermally stable mica withstand overload currents while preventing inter-segment flashovers.

Slot-Aligned Winding: Precision-positioned wave windings ensure optimal brush contact at magnetic neutral axis, maximizing output potential while minimizing short-circuit losses.

Odd-Slot Configuration: Exclusively employs odd-numbered commutator elements to prevent closed-loop failures in permanent magnet applications.


• Single-turn heavy-gauge conductors for high-current industrial drives
• Multi-turn fractional-pitch coils enhancing torque uniformity in servo systems
• Press-fit commutator construction maintaining bar integrity
• Laser-calibrated brush holders compensating for thermal expansion drift

 

Dynamic neutral-plane tracking during load fluctuations

Embedded test points for real-time EMF verification

Rigid shaft grounding dissipating electrostatic charges

Accessible undercutting ports for mica maintenance

Validated for traction locomotive starter motor and industrial generators, it achieves conversion efficiency through geometrically optimized winding-commutator alignment. All assemblies undergo high-potential testing to validate slot-to-bar indexing prior to dynamic balancing.

 

Dynamic Pressure Control: Maintains contact force across all speeds, ensuring uninterrupted power transfer under aerodynamic loads.

Carbon-Copper Compatibility: Monoblock carbon sliders minimize wear on copper/alloy catenary wires while suppressing electrical arcing.

Zigzag Wear Optimization: Guided head movement distributes abrasion evenly across  slider surfaces per span.

Single-Arm Aerodynamics: Streamlined frame reduces air turbulence at operations.

 

• TSG3/DSA-compatible mounting interfaces for locomotive and EMU applications
• Aluminum alloy spreader with fatigue-resistant hinges
• Moisture-shedding insulation for all-weather reliability
• Real-time contact loss detection via voltage sensors

Why choose Simo Brand Z DC Motor?

Simo ZTP series raiway DC motor is developed by Simo technical team and authorized and leaded by China Railway Ministry. It has been applicated in a series of well-known railway trains, such as FUXING, HEXIE, and many other trains for foreign countries. 

 

ZTP motor has outstanding advantages of high stator space utilization, small volume, small moment of inertia, good dynamic performance, and can withstand pulse current and high current rate of change. 

 

The motor can bear the impact and vibration generated during the normal operation of locomotives and vehicles. When the locomotive is exposed to rain and snow, the motor runs normally.

 

Great quality is the secret that Simo motor can be outstanding all through the 67 years in electric motor manufacturing industry. We have really strict control systems on the material suppliers choosing and reviewing, material inspection, processing checking, motor testing, testing , packing and transporting.
