The PM motor was designed in collaboration with Visedo and allows for a much lower mounting height. On average, a PM motor is 40% to 60% more compact than an asynchronous motor. The permanent magnet (PM) motor is seamlessly integrated into the thruster, resulting in a highly compact design. When combined with the special mounting method, precise headset alignment, and adjustments to the control box, it ensures optimal performance. The design makes use of every millimeter, without compromising quality.

The Veth Integrated L-drive provides for quiet operation while maintaining efficiency and reliability.

The Veth Integrated L-drive ‘s noise reduction features.

1. Gear Transmission Elimination:
   • Unlike some other propulsion systems, the Veth Integrated L-drive does not have a gear transmission within the ship.
   • This absence of gears significantly reduces noise production.
2. Water-Cooled Permanent Magnet (PM) Motor:
   • The L-drive incorporates a water-cooled PM motor instead of the traditional air-cooled asynchronous motor.
   • Water cooling is more efficient and quieter, contributing to noise reduction.
3. Electrical Steering:
   • The L-drive system utilizes electrical steering rather than hydraulic steering.
   • Electrical systems tend to be quieter, further enhancing noise reduction.

L-Drive Efficiency:
An L-drive, having only one gear transmission, inherently achieves higher efficiency. Specifically, the permanent magnet (PM) motor used in the L-drive is more efficient, especially during part-load conditions, compared to an asynchronous motor. At e.g. 25% load, there is an improvement in efficiency of 5.2%.
