Motor with Integrated Sensor Unit for Pressure and Volume Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fan and motor systems require complex mounting and wiring for pressure and volume flow control, involving separate electronics and external power supplies, which is time-consuming and costly.
Innovation Solution
A sensor unit is integrated into or plugs into the motor electronics, receiving power from it, allowing direct communication with the motor controller via a bus system, enabling internal pressure measurement and control without external wiring or power supplies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate control electronics and external power supplies are used for pressure and volume flow control, then measurement and control functions can be achieved, but mounting complexity and wiring requirements increase significantly
Solution Approach 1:
The patent combines the sensor unit with the motor electronics into a single integrated module. The sensor unit is plugged into the motor electronics, sharing the same housing and power supply connections. This merging eliminates the need for separate control electronics and external power supplies, directly reducing mounting complexity and wiring requirements while maintaining pressure and volume flow control functionality
Solution Approach 2:
The motor electronics are designed to serve multiple functions: driving the motor and housing the sensor unit for pressure and volume flow control. The single integrated module performs both motor control and environmental control functions, reducing the overall system complexity while achieving reliable measurement and control
2Measurement precision
If separate control units and external power supplies are used, then measurement functions are achieved, but installation time and cost increase
Solution Approach 1:
By integrating the sensor unit into the motor electronics, the patent reduces the number of separate components that need to be mounted and wired. The sensor unit shares the motor's housing and power connections, eliminating the need for separate mounting brackets, power supplies, and wiring harnesses, thereby significantly reducing installation time while maintaining precise air pressure measurement capability
Solution Approach 2:
The sensor unit is pre-integrated into the motor electronics assembly during manufacturing, with all necessary electrical connections and mounting arrangements already in place. This preliminary integration means that during installation, the entire motor-electronics-sensor assembly can be installed as a single unit, dramatically reducing on-site installation time and complexity

AI summary
A motor for a fan, a ventilator, a pump or a compressor includes integrated motor electronics and at least one sensor unit for pressure or volume flow control. The at least one sensor unit may be a module that can be plugged onto or into the integrated motor electronics or may be at least partly integrated into the motor electronics. The motor may be an electronically commutated motor. The integrated motor electronics may be configured to supply the at least one sensor unit with energy.
