EPMS Hydraulic Motor

LöSi^® hydraulic motors type EPMS^® are geroller motors of the heavy series. On EPMS^® geroller motors, the valve control is located in the end cover. The distributor valve or poppet valve is driven synchronously with the gear set so that the filling and emptying of the individual chambers takes place precisely and without losses. The poppet valve is separate from the output shaft and is driven by a short cardan shaft (valve cardan shaft). A balance plate balances the hydraulic forces around the poppet valve and thus guarantees high efficiency.
All geroller motors have additional rollers in the planetary gear set. This improves the starting behaviour of the motors (rolling friction instead of sliding friction). The EPMS^® hydraulic motors are available in different versions, for example with tacho shaft, brake or speed sensor.
