The invention concerns an arrangement for fastening of electrical and/or electronic power components to a circuit board, wherein the electrical and/or electronic power components () are mechanically and removably fastened to the board (). The power components () have plug and/or terminal connection elements () for their electrical connection and can be connected electrically to the board () via electrical lines, preferably with plug and/or terminal strips () arranged on the board ().

Housing for fastening of electrical and/or electronic power components to a circuit board

An asynchronous motor for a drive mechanism, in particular a hoist or a running gear includes a motor housing with opposite end faces covered by respective end shields, and an annular short-circuit winding disposed on a motor shaft. An asynchronous motor of this type is compact and inexpensive to manufacture and can be reliably controlled even in the presence of a rear-mounted magnetic brake, by accommodating in the motor housing at least two sensor units which are arranged sequentially in the direction of rotation of the motor at the rear of the motor housing, with each sensor unit including an opto-electronic receiver and a confronting electro-optic transmitter. Secured in the motor housing on the motor shaft between the short-circuit winding and the rear end shield is a circular rotary disk which includes modulation elements for interaction with the sensor units, by modulating the intensity of optical output signals produced by the electro-optic transmitter when the modulation elements pass by the respective sensor unit. The associated receiver transforms the modulated intensity of the optical output signals for formation of at least one electric motor control signal.

Asynchronous motor for a drive mechanism, such as hoists or running

A cost-effective ergonomic shaped suspended control panel for remotely controlling machinery, such as hoists or cranes. The suspended control panel has two curved housing portions and a curved circuit card mounted in the interior of the curved housing. Keys are mounted to the front side of the circuit card and switching devices are mounted to the back side of the circuit card. An electric line, supported by a cable, is electronically connected to the circuit card, the keys and the switching devices. The control panel is easily assembled through use of plug sockets for connecting the switching devices to the circuit board. Each plug socket is mounted with spring clamps which extend through the circuit card for wiring.
