Geared Motor has overall length of 186 mm.

Press Release Summary:




TPM 50 geared motor rotary actuator incorporates ac servo motor and high-precision planetary gearing. Maximum output torque is 500 Nm at mass moment of inertia of 2.9 kgcm². Low-speed motor reduces rotor inertia, while mass inertia is reduced on gear side by integrating pinion directly into motor shaft, thus eliminating need for clutch. With load inertia of 150 kgcm² at output, loads can be moved through 180° in less than 150 msec.



Original Press Release:



Operation of Alpha's Small and Highly Dynamic Gearmotor TPM Is Simple and Reliable, Commissioning Even More Convenient



The TPM has been developed as a product representing the highest level of integration. The TPM is a geared motor (rotary actuator) based on an AC servo motor and high-precision planetary gearing. The size of this compact unit is less than half compared to a conventional motor and gear combination.

The TPM rotary actuator is characterized by an extremely high dynamic response: with an overall length of 186 mm , the TPM 50 builds up a maximum output torque of 500 Nm at a mass moment of inertia of 2.9 kgcm² - until now impossible values.

This high dynamic response is due to the considerable reduction in the moment of inertia: the mass moment of inertia of the actuator has simply been reduced by 50% compared to a conventional solution with separate motor and gear unit. The reason lies in its design: the rotor inertia is considerably reduced by the low-speed motor and the mass inertia on the gear side is reduced by around 90% because the gear pinion is directly integrated into the motor shaft, thus eliminating the need for a clutch. Example: with a load inertia of 150 kgcm² at the output, loads can be moved through 180 degrees with utmost precision in less than 150 milliseconds.
