Abstract: A common mode choke (64) comprises a magnetic core (58) and a first (Wab) and a second (Wcd) winding of insulated wire having the same number of turns wound on the magnetic core. The turns of each winding are numbered consecutively and arranged in at least two layers, of which a first layer of turns is wound directly on the magnetic core and a second layer of turns is wound around a section of the first layer. The two layers are arranged such that the difference between the highest number of a turn in the second layer and the lowest number of a turn in the section of the first layer on which the second layer is wound is less than or equal to 50% of the number of turns in the first layer. In this way, the effect of the parasitic capacitance between the layers is minimized.

Abstract: Emergency stop for a linear actuator system, which comprises a housing (13) and an activation button (12) adapted for activating a circuit breaker and where the activation button (12) has a neutral position and an emergency position. The emergency stop further comprises a spring (19) for spring-loading the activation button (12) for retaining the activation button (12) in the neutral position, a latching mechanism adapted for retaining the activation button (12) in the emergency position once it has entered this position, and a release mechanism adapted to unlatch the latching mechanism. The spring-loaded activation button (12) is pivotally connected to the housing (13) and arranged to pivot between the neutral position and the emergency position. The spring-loaded activation button (12) comprises an arm (26,27) having one end attached to the underside (24) of the spring-loaded activation button (12). The housing 13 comprises a wall piece (35,36) adapted for engaging a free end of the arm (26,27). The latching mechanism comprises a protruding part (61,62) on the arm (26,27) and a receiving part (39,40) on the wall piece (35,36), said protruding part (61,62) and said receiving part (39,40) being unlatched when the activation button (12) is in the neutral position and latched when the activation button (12) is in the emergency position. The release mechanism comprises a reactivation button (14,15) movable between a first and second position, said reactivation button (14,15) unlatches the latching mechanism by disengaging the protruding part (61,62) from the receiving part (39,40) when the reactivation button (14,15) is moved from the first position to the second position.

Abstract: A frame for sit-stand-tables comprising a longitudinal member, two height-adjustable legs with at least two telescopic profiles, namely an outer and an inner profile, and with a driving mechanism, driven by a motor unit, comprising an electric motor and a gear. According to the invention the motor unit is arranged in the longitudinal member and connected to the driving mechanism in the height-adjustable legs. Thus, a frame with a simplified construction is achieved. The construction of the legs can be simplified and at the same time the dimensions can be reduced, as it is not necessary to take the building-in of a motor into the legs into consideration. As both legs are driven by a joint motor unit, the electric control can also be simplified as it will not have to drive the two legs synchronously.

Abstract: The present invention relates to a linear actuator with an improved electric motor. In particular, the invention focuses on improved technical solutions for braking or locking of a rotating electric motor by using an electro-mechanical locking mechanism. The mechanism uses a solenoid having a nonrotating locking element, which is displaceable by solenoid action and arranged to engage with a rotating locking element. In particular, solutions have been found in which a surprisingly small solenoid with a much-reduced requirement on stroke length may be deployed to effectively unidirectionally or bidirectionally lock against rotation of the motor.

Abstract: Control unit (7), especially for a patient lift (1) comprising a base (10) and a power supply (8), said power supply (8) is releasably mounted on the base (10), and comprising locking means for retaining the power supply (8) on the base (10). The locking means comprises a set of slots and protrusions (17,18;20,22) on the base (10) and the power supply (8) and where the protrusions and slots engage each other, when the base (10) and the power supply (8) is displaced sideways in relation to each other. A tab (27) is arranged on an arm (24) of the locking handle (23). The tab (27) goes into the gap (28) between the base (10) and the power supply (8), when the locking handle (23) is locked. Thus, the protrusions (17,20) and slots (18,22) are in engagement with each other and at the same time functioning as a locking mechanism.

Abstract: Linear actuator (8) comprising a quick release (27) for disengagement of an adjustment element (23) from an electric motor (19) and the part of a transmission (20) extending from the electric motor (19) to the quick release (27), such that the spindle (21) of the linear actuator is rotated under the load on the adjustment element (23). Further, the linear actuator comprises brake means (28) connected to the spindle (21) for controlling the speed of the adjustment element (23), when the quick release (27) is activated. A coupling (34;52,53,54) connected the brake means (28) is configured to set the brake means (28) in an active state, when the coupling (34; 52,53,54) is engaged, or in an inactive state, when the coupling (34;52,53,54) is slipping or disengaged.

Abstract: Linear actuator comprising a housing (1) consisting of two parts (1a, 1b), an electric motor (3) with a motor shaft, a transmission (8-11) in connection with the motor shaft, a spindle unit in connection with the transmission, where the spindle unit comprises at least a spindle (7) with a spindle nut (14) and where the spindle (7) is equipped with a bearing (12), an adjustment element (13) in connection with the spindle unit. The linear actuator is characterized in that a mounting unit (2) is embedded in the housing, said mounting unit (2) has a front and a rear end, and where the motor (3) is placed on the rear end of the mounting unit (2) and the spindle (7) is mounted on the front end of the mounting unit (2), and where the transmission (8-11) is located inside the mounting unit (2). In addition to being able to reduce the number of components with this construction, e.g. the activation element (13), the front mounting (15) and the spindle nut (14) can be moulded as one single plastic unit, it also allows for a slackening of the tolerances as the assembly of the components is considerably simplified, namely only with regard to the mounting unit (2). In that connection, the transmission (8-11) is expediently placed in the mounting unit (2).
