Welcome to Merkes GmbH
Synchronous Servomotors of Series MN – MT – MTK
Standard Design
Today we mainly supply as a strategically partner automation and system houses which in full or supplementary satisfy their own needs of motors out of our delivery program. The brand labeling of the servomotors incorporates these into the company’s own drive engineering and so the circle is completed right to the complete servo axis for use in the final application. But also the classical machine builders our servomotors combined with servo amplifiers of either own production or bought in addition.
Customized Design
Being one of the rare European Motor Producer we also develop and build customized servomotors of small and medium sized series. Hundreds of variants of windings and mechanical designs set our customers in a leading position by having their individual servomotor in comparison to the markets standard.
IE4 Motors / IE5 Motors of Series MPM
By now even efficiency class IE5 !
The advanced motor concept of series MPM allows higher speed and torque in combination with a smaller motor design and lower losses. Even today the challenges of the future as efficiency class IE5 ultra premium efficiency are achieved. The synchronous motor technology in a classic standard motor housing fulfills the economic requirements and making it ideal for speed controlled operations or applications with high duty cycles and/or high partial loads. The series MPM reduces the number of types, cuts down weight and saves energy.
Standard Design
The IE4 Super Premium Motors and IE5 Ultra Premium Motors of Series MPM are brushless permanent magnet synchronous motors with buried permanent magnets in the rotor. Designed for operation in star or delta connection at a frequency inverter with a supply voltage of 400 VAC having a „Sensorless-Vector-Control“ regulatory procedure. The motor has no brushes, the commutation is electronically done by the corresponding inverter. A fan is mounted on the B-side of the shaft which provides a speed dependent cooling of the motor.
Customized Design
Based on the concept of the series MPM the flexible inhouse production of all components provides the possibility to build customized motors according the electrical and mechanical requirements of an application. Typically larger series are needful to take economical and technical advantages of the serial production.
IE5 Synchronous Reluctance Motors
At this motor design no rare earth magnets are used in or on the rotor. The torque is generated by the reluctance force (magnetic resistance). Compared to asynchronous motors the IE5 synchronous reluctance motors offer high efficiency IE5 Ultra Premium at nominal load and especially at partial load. In principle the synchronous reluctance motor combines the physical principle of the asynchronous motor with that of the synchronous motor. These can replace the asynchronous motor in applications with variable speed and pay off when operation is associated with high energy costs. This is the case with pumps and fans for example which often operate continuously.
Standard Design
The standard versions complement our range of synchronous motors in large sizes and come from a cost-optimized series production of a so-called “Global Source Partner” outside the EU. The standard versions are primarily used when motors with lower energy efficiency are to be replaced by highly efficient motors. This makes them particularly suitable for modernizing existing systems and machines (keyword: Ecodesign Directive).
Customized Design
We of course like to check the technical and economic feasibility of special designs based on the concept of the series production mentioned above.
