1 Brush DC Motor Runs Along (August 2013)

Everything started in 1800 when Volta developed the first DC battery. Faraday used the DC battery to develop the first electric motor. It used brushes to transfer the battery voltage and current to the rotating disk rotor. This was in mid-1831. Thus was born the brush DC motor.

2 Development of the Upgraded DC Brush Gearmotor for Spacebus Platforms (April 2011)

The obsolescence of materials and processes in the manufacture of traditional DC brush gearmotors has necessitated the development of an upgraded DC brush gearmotor.

3 How to Select a DC Motor: Coreless and Iron Core Brushed DC Motors (June 2017)

DC motors possess linear relationships that allow for very predictable operation. For instance, if enough voltage is applied across the terminals of a DC motor, the output shaft will spin at a rate proportional to that applied voltage. You can take the ratio of the applied voltage over the rated voltage and multiply that number by the no load speed and get the running speed.

4 DC Motor Protection (June 2013)

The purpose of DC motor protection is to extend a motor's lifespan by protecting it from conditions that can damage the motor's windings--both electrically and mechanically.

5 The Painful Birth of the DC Electric Motor (June 2012)

Defined in rudimentary terms, an electric motor is a device that uses electricity to create mechanical force. But in 1834, when our story takes place, most people would have trouble understanding the ramifications. That was the year that one of the earliest DC electric motors was invented—by a blacksmith.

22 Bringing Nadcap to the Medical Industry (June 2016)

The medical device industry today has numerous standards and regulations to follow, most notable amongst them being ISO 9001 and ISO 13485. However, these requirements have a shared blind spot: critical processes (heat treating, sterilization, etc.). In the medical industry, all of the standards and audits suppliers need to adhere to focus on general system quality. If the critical processes aren’t being looked at equipment can still fail because of poor craftsmanship.

23 Lightweight, Highly Efficient Drive System (February 2017)

This paper presents a joint project conducted by Ashwoods Electric Motors and Oerlikon Fairfield that uses planetary drives with an integrated electric motor. Current solutions used in production of off-highway vehicles rely upon large, heavy and inefficient brushed DC or induction motors, coupled to a planetary gearbox. This presents a number of challenges to the vehicle designers such as: limited vehicle range, limited space around the motor/drivetrain, and motor durability. The proposed integrated system utilizes an Oerlikon Fairfield Torque Hub, widely used in off-highway vehicles, and the Ashwoods first-to-market, interior permanent magnet motor. How these products are integrated, i.e. incorporating a brake solution, represents a market-changing product. Using interior permanent magnet (IPM) technology in the motor design means the motor can be up to 70% lighter, 70% smaller and 20% more efficient than traditional motors used in off-highway traction applications.

24 Nervy Enterprise and Edgy Engineering: A Cant-Miss Mix (June 2012)
