Single-Motor Direct Replacement for Dual-Starter Data Center Generators

Data Center

Application Overview

High-capacity generator sets in data centers often use two starters in parallel to provide enough cranking power for large-displacement engines. HEXASTART’s 11 kW high-torque electric starter, the QD21129, offers an alternative to this layout. With high initial breakaway torque, a single starter can replace the traditional dual-starter setup, giving data center operators a simpler, space-saving and installation-flexible starting solution for mission-critical applications.

Key Advantages for Data Center Installations

  • Single Starter in Place of Twin Starters: One starter delivers the breakaway torque needed to drive large-displacement gensets, replacing the conventional parallel dual-starter arrangement.
  • Lower Cost of Ownership: Using one starter instead of two can reduce procurement cost, spare-parts inventory and maintenance workload.
  • Space-Saving & Flexible Mounting: No second starter bracket is needed, which saves space in the engine bay and simplifies layouts in tight or non-standard enclosures.
  • Simpler Electrical Layout: One starter means one set of relays and wiring instead of two, reducing the number of potential electrical failure points.
  • OEM & Retrofit Integration: Matched to engines such as the Mitsubishi S16R, with standard SAE interfaces and custom development available for other engine models and flywheel housing requirements.
