BLDC Motor Driven Pumps
Secondary Air Pumps and Systems
The Business Unit Emission and Thermosystems develops and manufactures components for fresh air injection in exhaust gas treatment systems. These include valves with a choice of electric or pneumatic actuation.
The portfolio offers blowers with constant speed using DC motors or variable speed using brushless DC motors (BLDC). Potential applications include the acceleration of catalytic converter heat-up for cold starts or controlled particle filter regeneration.
blDC Motor Driven Pumps
In contrast to air pumps with DC motors, the speed of brushless DC (BLDC) motor-driven air pump is variable. This is why they are always used when a variable air flow is required, for example in applications with long power-on cycles and variable operating conditions.
