With direct tool mounting
We offer a wide range of electric motors for customized drive solutions in a wide variety of industries and applications – developed and manufactured at our site in Mannheim.
Our wide range of variants and the flexible modular design features that go beyond the possibilities of conventional standard motors and are unique in this combination.
Customer-specific shaft designs with concentricity and axial run-out accuracy in the µm range as well as high-speed direct drives for challenging applications such as milling, sawing, drilling, grinding or in process engineering are our core competencies.
Our power range includes:
- Motor power from 200 W to 200 kW
- Speed up to 36,000 rpm
- Manufacturing from prototypes to series production
Customized solutions for:
- Shaft design
- Electrical design and connection
- bearing
- seal
- cooling
- sensor technology
Perske realizes the ideal drive of high-speed special motors and motor spindles, also as compact solutions in synchronous technology – with customized features.
