Document Type and Number:
WIPO Patent Application WO/2013/161361
Kind Code:
A1
Abstract:
The present invention is equipped with: a hydraulic pump (2); an induction motor (1) that drives the hydraulic pump (2); a coupling (3) linking an output shaft (1a) on the induction motor (1) and an input shaft (2a) on the hydraulic pump (2); and an encoder (4) attached to the coupling (3) and used to detect the rotational frequency. Thus, the encoder that detects the rotational frequency of the induction motor driving the hydraulic pump can easily be attached, and a general-purpose induction motor can be used as is, thereby making it possible to provide a hydraulic device with a reduced cost, and a molding machine using this hydraulic device.
