Water cooled motors for compact spaces launched

The three-phase asynchronous motors are suited to applications where high performance is a requirement, but noise and heat must be kept to a minimum, such as in small spaces, including cleanrooms.

“With our WD model, you can achieve significant reduction of the footprint on people and the environment through noise emissions and heat dissipation,” said Detlef Koslowsky, head of sales at Ben Buchele.

“As opposed to air-cooled motors, water-cooled motors do not cause swirling of dust or dirt, making them the ideal solution for hygienically critical areas. The S1 duty cycle means that the motor runs continuously, which is important for these types of application.”

Compact motors

The new range of motors is available globally in 0.75 to 300 kW capacity.

Starting with the WD71 model and going up to the WD315; WD is a reference to ‘water-cooled’ in German, while the numbers represent the motors’ frame size. The dimensions of the products vary as the motors increase in frame size in 13 total increments, including 80, 90, 100, 112, 132, 160, 180, 200, 225, 250, and 280.

Koslowsky said the range will be sold to both original equipment manufacturers (OEMs) and end users, with test facilities, printing devices, textile machines, injection machines, maritime hybrid engines and anchor / mooring winches, among target applications.

Depending on the end use and customer preference they can be supplied coated, or painted in white, which will likely be the chosen option for those utilising them in food production environments.

The new water-cooled (or WD) range can be used in the most challenging conditions, such as those where seawater, salty air, and ambient temperatures of up to +60°C are present. Manufactured with high-quality, application-sensitive seals and sealants, they can achieve protection levels according to IP56, 66, or 67, depending on the motor.

While the range is standard based on frame size and capacity, each unit is prepared accordingly to individual specifications. With the variable multi-foot attachment and adjustable casing, the shape of the motor can even be modified multiple times, including onsite. The coolant supply openings are located on the non-driving side to allow for further ease of modification. The performance range reaches currents up to 690V, for operating modes of S1-S9, regardless of whether the motor is then operated at 50 / 60Hz or using a frequency converter:

Ben Buchele is increasingly focusing on the US market and will exhibit at the International WorkBoat Show which takes place in New Orleans, Louisiana, on 30 November to 2 December.
