Publication number: 20100192836Abstract: An indicating instrument for a vehicle includes a step motor including a field winding, a pointer, a stopper device for stopping the pointer, which is rotating in a zero-reset direction, at a stopper position, a detecting device for detecting induced voltage of the field winding at each of detecting points, a control device for performing zero-reset control, whereby a drive signal is controlled to rotate the pointer in the zero-reset direction. In a state of abnormal detection in which the induced voltage larger than a predetermined set value is detected at a zero point; and the induced voltage equal to or smaller than the set value is detected at a next detecting point to the zero point, the control device assumes synchronization loss of the step motor and continues the zero-reset control until an assumptive electrical angle corresponding to a rotational position of the pointer reaches the zero point.Type: ApplicationFiled: February 4, 2010Publication date: August 5, 2010Applicant: DENSO CORPORATIONInventor: Hideyuki Nakane

Patent number: 7730848Abstract: The invention relates to an indicator apparatus (1) having a ring pointer (2), which is mounted such that it can move in the circumferential direction (5), and having a drive unit (3), which drives the ring pointer (2) in the circumferential direction (5), wherein the ring pointer (2) interacts with a stop (10) in a manner limited in terms of its circumferential movement. Particularly in the case of synchronization, radial disengagement often occurs in conventional ring pointer arrangements, and the aim of the invention is to prevent this. In order to solve the problem, the invention proposes arranging the stop (10) directly next to the drive unit (3). The critical advantage of this is that the tangential force on the ring pointer (2) from the drive unit generates an only small disengagement moment on the ring pointer (2).Type: GrantFiled: September 21, 2006Date of Patent: June 8, 2010Assignee: VDO Automotive AGInventor: Axel Förster

Patent number: 5847531Abstract: A process for reducing the strength of an uncontrolled movement of a pointer driven by a stepper motor and abutting against a mechanical stop means when the stepper motor is switched off. Prior to the switch-off operation, the field strength of the magnetic field of the stepper motor is lowered, or the pointer is moved away from the stop means by a specified compensating angle of rotation. Alternatively, following the switch-off operation, the stepper motor is switched on again at least one time following a specified time span for a specified switch-on time span.Type: GrantFiled: February 29, 1996Date of Patent: December 8, 1998Assignee: Moto Meter GmbHInventors: Klaus Hoffsommer, Roland Steger, Bernhard Herzog

Patent number: 4646007Abstract: The zero position in a sine cosine indicator for a tachometer is determined by a projection on the magnetized rotor arranged to encounter a stop projecting from the enclosing bobbin wall. A weak stationary secondary magnet is located adjacent the rotor with the magnetic axis of the secondary magnet rotated through an angle less than full scale from the magnetic axis of the rotor when the rotor is in the zero position. Alignment and crossover between the two magnetic axes is arranged to occur when the pointer associated with the rotor is approximately at midscale. Consequently any distortion of the scale to either side of the crossover point is in opposite directions and the overall appearance of the scale to the casual observer is linear.Type: GrantFiled: March 25, 1985Date of Patent: February 24, 1987Inventor: Thomas G.

Patent number: 4425864Abstract: A rotor for an electromagnetic indicator comprises a flat circular disk made of thin, pliable, nonmagnetic material. The disk has integral tabs extending out of diametrically opposite edges and a rib extends diametrically of the disk to outer ends of the tabs. The rib and tabs define T-shaped trunnions which engage in T-shaped slots in respective sides of a rotary magnet, and a journal block. The disk is fabricated from a single flat sheet having flat tabs extending outwardly of opposite edges. A V-shaped groove is made in the sheet extending centrally across the disk and tabs. Opposite sides of the groove are then brought together to form the rib with T-shaped trunnions at opposite edges of the disk.Type: GrantFiled: February 5, 1982Date of Patent: January 17, 1984Assignee: The Staver Company, Inc.Inventor: Alfred Skrobisch
