DIRECT DRIVE TORQUE MOTOR

PERMANENT MAGNET SYNCHRONOUS MOTOR (PMSM)

A direct drive torque motor is a permanent-magnet synchronous motor (PMSM). Hence, the load is directly driven without the use of a gearbox or transmission. This reduces the number of moving parts, and thereby increases the operational lifetime and efficiency of the application. Compared to induction motors with the same volume/weight, the peak point energy efficiency of frameless high torque motors is much higher.

Magnetic Innovations offers a wide range of standard frameless high torque motors, including both outrunner and inrunner types. Our Frameless Torque Motors Series are designed to be integrated into systems, offering reduced size and weight, making them highly versatile for various applications.

UNMATCHED PERFORMANCE

Direct drive motors are ideal for applications where a high positioning accuracy is needed and small size, low weight, minimum power and optimal speed control is desired. With the use of our magnetic and thermal simulation software, our frameless high torque motors are designed to produce unmatched performance.

Magnetic Innovations offers both outrunner and inrunner torque motors, each optimized for different application needs. Outrunner motors are known for delivering higher torque and efficiency, while inrunner motors excel in applications where compactness and precision are key advantages. This allows us to provide the best solution for a wide variety of industrial and technical requirements.

To maximize the torque of our direct drive motors, we use innovative winding configurations combined with optimized permanent magnet technology. A 3-phase sinusoidal current amplifier can be used in combination with the torque motor, which guarantees smooth rotation with low torque ripple.
