Interference-suppressed linear drive

A linear drive comprising:

• a transmission housing,
• a motor housing,
• a rotor accommodated in the motor housing,
• a shaft which is mounted on a rear shaft end in a rear shaft bearing and is mounted on a front shaft end,
• an interference-suppressed electric motor which is connected to the transmission housing and is accommodated in the motor housing and, by way of the rotor, drives the shaft,
• a commutator for current transmission to the rotor, electrical and/or electronic components for interference suppression of the electric motor,
• wherein the shaft by means of a worm drives a transmission arranged in the transmission housing for displacement of a lift tube guided longitudinally displaceably in a guide tube,
• wherein the rear shaft bearing is mounted in the motor housing, the front shaft bearing is arranged or mounted in the transmission housing and the electrical and/or electronic components required for interference suppression of the electric motor are arranged on an interference suppression circuit board arranged between the front shaft bearing and the commutator.
