Motor/Generator

	All the advantages of a brushless motor with the simplicity of a DC motor

Materials and construction

The stator is made from 29 gauge, M15 electrical steel laminations, which are stacked and bonded.  Trapezoidal bars of aluminum are inserted into the stator core, exceeding 90% slot fill (compared to less than 50% for motors with traditional copper windings).

The rotor is made from precision machined steel bar and has twelve high-temperature (180°C) neodymium-iron-boron (NdFeB) magnets mounted on its circumference.  The magnets are retained with stainless steel bands and the rotor is balanced prior to assembly.

Following our commitment to high quality, high performance materials and components, Nachi bearings are used throughout our product line.  30mm double-row angular contact bearings are standard.

The rear cover is comprised of glass-filled, high temperature thermoplastic, which is precision machined.  A magnetically coupled coolant pump may be added, when necessary.

SolidSlot Construction

eCycle SolidSlot Advanced Brushless Motor/Generator  Technology

Electronic Commutator

Integrated electronics are mounted on the rear cover and cooled with a brushless fan. This enables the SolidSlot  brushless motor to be run directly from a battery or with an industry standard DC motor controller. 

For increased flexibility, the electronic commutator can be mounted remotely and cooled by air or liquid.

Utility 

A broad range of configurations are possible, some as simple as adding the desired shaft adapter.  In general, the SolidSlot™ can support a broad range of applications, including mobile hydraulics, marine propulsion and generation, robotics, integrated  starter/alternators, diesel, gasoline and gaseous fuel gen-sets, and large centrifugal pumps. 

Power Generation

As a result of the electronic commutator, the SolidSlot™ brushless motor/generator may be used to directly produce DC power through high efficiency synchronous rectification.  The voltage is proportional to speed and the resultant DC power may be used for battery boosting or to power an AC inverter.  More information can be found on the APU page.
