Electric Motor Brake Release via Conduction Bypath
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric motor systems with integrated brakes face challenges in efficiently releasing the brake from the braking state without activating the driver, especially when the motor is being fitted into an apparatus and requires manual adjustments, often necessitating complex signaling and component management.
Innovation Solution
The electric motor system incorporates a driver with a first circuit and a conduction path that allows electric power to be supplied to the brake even when disconnected from the main power line, enabling the brake to switch to the release state through a portion of the power line, thereby simplifying the release process and reducing component complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver is activated to release the brake, then the brake can be reliably released, but the component count and operational complexity increase
Solution Approach 1:
The brake release function is achieved through the existing power line connection without requiring driver activation. The brake coil receives power directly from the power source through the power line, allowing the brake to release itself without external control signals or driver intervention, thereby simplifying the system while maintaining reliability
Solution Approach 2:
The power line is designed to serve dual purposes: it provides power to the motor during normal operation and simultaneously provides power to the brake coil for brake release. This multi-functionality eliminates the need for separate control circuits or additional components dedicated solely to brake release
2Device complexity
If the driver is not activated for brake release, then component complexity is reduced, but the ability to control brake release becomes limited
Solution Approach 1:
The system allows dynamic brake release by enabling power flow to the brake coil through the existing power line infrastructure. The brake can be released at any time by establishing the appropriate electrical connection through the power line, providing operational flexibility without requiring complex control mechanisms

AI summary
An electric motor system includes an electric motor, an electric brake, a power line, and a driver. The electric brake is integrated with the electric motor and configured to generate braking force against the drive force. The driver is integrated with the electric motor and the electric brake. The power line connects the electric brake to an electric power source via the driver to supply electric power to the electric brake. The driver includes a first circuit and a conduction bypath. The first circuit connects the electric brake to the power source such that electric power is supplied to the electric brake and disconnects the electric brake from the electric power source. Electric power is to be supplied to the electric brake from the electric power source through the conduction bypath even when the first circuit disconnects the electric brake from the electric power source.
