The Multiquip B5110000402 Rotor Assembly is a genuine OEM component designed for Multiquip super-silent and ultra-silent generator models including the DCA36SPXU4F, DCA70SSIU4F, DCA70USI2, DCA70USI3CAN, DCA70SSIU2, and MQP56 series. As a factory-sourced part, it is manufactured to the exact tolerances required by Multiquip to maintain proper alternator output and electrical performance. Sourcing the correct rotor assembly is critical — an incorrect or worn rotor can result in unstable voltage output, reduced power generation capacity, or complete alternator failure. DHS Equipment stocks this part to help keep your Multiquip generator operating at its rated performance level.
Key Features
- Exact Alternator Tolerancing — Wound and balanced to OEM specification, ensuring the rotor spins true within the stator and delivers consistent magnetic field strength for stable voltage output.
- Genuine OEM Part — Sourced directly from Multiquip, this rotor assembly carries the same part number (B5110000402) used by authorized Multiquip service centers.
- Broad Generator Fitment — Compatible with DCA36SPXU4F, DCA70SSIU4F, DCA70USI2, DCA70USI3CAN, DCA70SSIU2, and MQP56 series Multiquip generators.
- Stable Power Output — A correctly functioning rotor maintains the rotating magnetic field that drives AC power generation; a failed or degraded rotor causes voltage drop, frequency instability, or total loss of output.
- Electrical Safety Compliance — As a core alternator component in commercial generator applications, using a genuine OEM rotor assembly helps ensure the unit continues to meet its rated electrical output and safety classifications.
The rotor assembly is the rotating core of a generator's alternator. It spins within the stationary stator windings, and the interaction between the rotor's magnetic field and the stator produces the AC electrical output the generator delivers. Over time, rotor windings can develop shorts or open circuits, and the rotor itself can become unbalanced, all of which cause measurable drops in power quality or output capacity. Replacing a failed rotor with a genuine OEM assembly restores the alternator to its original rated performance and protects the connected equipment from unstable power supply.
