Small drives are used today in various fields of application such as automation, packaging technology or laboratory and medical technology. Ebm-Papst has developed a drive family in the form of a modular system. A new 42 mm diameter drive complements the product range for applications with lower torque and power requirements.
The brushless, electronically commutated internal rotor motor is available with stator lengths of 20 and 40 mm. Thus, the small motor achieves performances of around 45 or 90 W at 110 or 220 mNm torque and 4000 min-1 Rated speed. Thus, these engines offer over the predecessor type a higher power density and almost twice the torque at around 40% less mass. The IP40 IP24 induction version is manufactured for nominal voltages of 48 and XNUMX VDC.
In the current version, a rotor position sensor with three Hall elements is installed in the circuit board of the motor. The drive is thus equipped for operation with external and customer-specific electronics. The drive energy is decoupled via a 8 mm strong shaft. The ball bearings of the gear modules are particularly robust for higher radial loads on the output shaft and are therefore suitable for applications with prestressing, for example for belt drives. Customer-specific variants for other shaft diameters, flange geometry, centering collar and modules for electronics, encoders and brakes are in preparation. This makes universal use of the ECI-42 drives possible.
