Function, Specifications, Materials, and Key Parameters of
DZ15221840402B Heater Blower Motor Assembly
1. Function
The DZ15221840402B heater blower motor assembly is a critical
component in the vehicle's heating, ventilation, and air
conditioning (HVAC) system. Its primary function is to drive the
blower fan, which circulates air through the heater core or
evaporator core to provide heated or cooled air to the vehicle's
cabin. This ensures passenger comfort by maintaining a desired
cabin temperature.
2. Specifications
• Part Number: DZ15221840402B
• Brand: Shaanxi Heavy-Duty Automobile or compatible with SHACMAN
vehicles
• Model: Designed for use in the HVAC systems of commercial
vehicles, such as the Shaanxi Automobile Delong series (e.g.,
F3000, X3000, M3000)
• Type: Heater blower motor assembly with integrated motor, fan,
and housing
3. Materials
• Motor Housing: Constructed from high-strength alloy steel or
aluminum alloy to ensure durability and heat dissipation
• Rotor and Stator: Made from high-grade electrical steel and
copper windings for efficient motor operation
• Fan Blades: Typically made from high-impact plastic or aluminum
to withstand high-speed rotation and airflow
• Bearings: Use high-quality ball bearings or sleeve bearings to
ensure smooth and quiet operation
• Seals and Gaskets: Made from rubber or polyurethane to prevent
air leakage and ensure airtightness
4. Key Parameters
• Rated Voltage: Typically 12V or 24V, depending on the vehicle's
electrical system

generally ranges from 50W to 300W for such applications
• Speed: The motor may have multiple speed settings (e.g., low,
medium, high) controlled by the vehicle's HVAC control module
• Air Flow Rate: The capacity to move air, which determines the
efficiency of the heating and cooling system (specific value not
provided, but generally ranges from 200 to 800 cubic feet per
minute (CFM) for commercial vehicle applications)
• Noise Level: Designed to operate quietly, with noise levels
typically below 60 decibels (dB) at maximum speed
• Operating Temperature Range: Designed to operate effectively in
various environmental conditions (specific value not provided, but
typically designed to operate between -40°C and +80°C)
• Mounting Type: Designed for easy mounting on the vehicle's HVAC
system, with specific mounting holes and brackets for secure
attachment
• Weight: The weight of the heater blower motor assembly may vary
based on materials and design, but it is typically compact and
lightweight for easy installation (specific value not provided, but
generally designed to be ergonomic and user-friendly)
