Electric Motors: Comparison

Electric power systems comprise a controller and a motor. A controller is a device or group of devices that governs the performance of an electric motor. A motor controller might include a manual or automatic means for starting and stopping the motor, selecting the forward or reverse rotation, selecting and regulating speed, regulating or limiting the torque and protecting against overloads and faults. PMAC Brushless

Inset BoltOne of the system’s unique features is its universality. The TREZIUM® System plugs into any outlet in the world with a simple plug change, operating at 50/60 Hz or, in aerospace, applications at 400Hz. In contrast, most others systems would require upwards of six different designs to meet world requirements.


Perfectly matched controller and motor.

The core of Thor Power’s TREZIUM® System is its microelectronic controller and permanent magnet motor. They are perfectly matched for maximum efficiency, power, and control. It’s the only unified system of controller/motor that uses a single printed circuit board controller with vector control to drive an AC, synchronous, sine wave, permanent magnet motor that is also brushless, slotless and sensorless in its range of power, and, it can be used worldwide.

The controller utilizes vector control, which contributes to the system’s exceptional torque control and high efficiency. It is an AC – DC – AC controller. (Thor Power can modify it into a DC – AC system for use in DC facilities.)

Superior in many ways.

The TREZIUM® System is superior to any other power system on the market. Other power systems have controllers and motors, and the controller and/or motor may have some of the positive characteristics of the TREZIUM® System but no other system has all of them. The two diagrams below demonstrate where the TREZIUM® System fits in the world of electric motors.
