An Open Source Motion API

Gary Box Digital Power Engineering www.digitalpowerengineering Abstract The advent of Machine to Machine (M2M) networking presents both an opportunity and challenge to the Motor and Drive industry, particularly for older applications that have yet to move to electronic control and higher efficiency motors. To get on the ‘Cloud’ these cost […]

Designing In-Hub Brushless Motors

Lowell Christensen, Founder, Vice President of Engineering TruTech Specialty Motors, Plymouth, MN Electric motors formatted to fit inside the wheel of a vehicle have their own special constraints that impact the design of propulsion systems. In-hub motors are traction motors in that they change rotary motion to linear motion. They are […]

  • Are You UL Listed? May 24, 2020
    After many years of working with various motor manufacturers, it is still surprising that so few customers understand the UL process. And for many of us, including our customers, it is not what we might have thought we were getting. I have known several people to use laboratories such as QPS, ...
  • Permanent Magnet Motors in Low Voltage High Speed Applications January 10, 2020
    TruTech Servo Motors & Systems This presentation will discuss the design issues of designing a permanent magnet motor to be used in low voltage applications. The major issue in these applications is the low inductance of these motors and the high currents required. This presentation will talk about these issues and ...
  • Permanent Magnet Brushless Servo Motors for Agricultural Applications November 2, 2019
    TruTech Servo Motors & Systems Electric motors have had use in agriculture type applications for many years. These applications have tended to be belt driven types with electric motors capable of only one speed. Any change in speed required needed to have the gear ratio changed. This has required other methods ...
