Entertaining Motion in Design
Designing a new DC servo motor drive using IPMs and an extended high gain observer to reduce quantization error, which helped their client to overcome the challenges they were facing.
Background
Our team has developed a non-hazardous, ozone-free, and environmentally friendly way to generate motion effects for film and video productions. Our client's 6DOF (six degrees of freedom) motion simulator uses a servomotor to create lifelike movement and realistic sensations for the user. The servomotor is driven by a DC motor drive, which was designed by our team.
The existing motion platform used PMDC (permanent magnet DC) motors, which are no longer manufactured. Our client needed a replacement for the discontinued motor, as well as a team with expertise in motor drives to design new drives for the platform.
Our team took on the project to design new motor drives for the existing motion platform. The team was able to design a circuit for the motor drive using IPMs (integrated power modules) and implement an extended high gain observer to reduce quantization error. This helped our client to overcome the challenges they were facing.
The client is a leading provider of 6DOF motion simulators for film and video productions. The company has been in business for over 10 years and has worked on projects for major Hollywood studios.
The Challenge
The client's existing motion platform used PMDC motors, which are no longer manufactured. The client needed a replacement for the discontinued motor, as well as a team with expertise in motor drives to design new drives for the platform.
Uncertainties
How We Helped
Innovolo took on the project to design new motor drives for the existing motion platform. The team was able to design a circuit for the motor drive using IPMs (integrated power modules) and implement an extended high gain observer to reduce quantization error. This helped our client to overcome the challenges they were facing.
The new motor drive circuit designed by Innovolo has helped the client to save money by reusing other parts of the existing motion platform. The design was also able to meet all the requirements of our client. In addition, Innovolo’s team gained valuable skills and experience in the field of motor drives which can be used for future projects.
