Product Description

The Dyson DC40 Motor (Panasonic) assembly, part number 921440-01, is the genuine OEM replacement motor for Dyson DC40 and UP16 corded upright vacuums. This Panasonic-manufactured motor drives the brush roll and suction system in DC40 models and is essential for restoring full vacuum performance when the original motor fails or loses power.

This is a direct OEM replacement part designed to exact Dyson specifications. The motor assembly includes the rotor, stator, and housing necessary for proper DC40 operation. Dyson DC series motors are not interchangeable across model lines—DC40 motors will not fit DC33, DC65, or other DC series variants.

Compatibility: Dyson DC40, Dyson UP16. This motor is specific to these models and will not work with DC33, DC65, V-series (cordless), or other Dyson corded vacuums.
