Title: Detecting method for position of rotor of brushless dc motor
Inventor: TAKAHASHI TOMOFUMI
IPC: H02P6/06
Filed: 1985-10-22
Abstract: PURPOSE:To detect the position of a magnet rotor for a motor stably by holding an induced voltage signal, amplitude thereof is limited, by a signal synchronizing with a commutation spike. CONSTITUTION:Voltage appearing at the neutral point of an armature winding for a motor 2 is divided by resistors R1, R2, and inputted to an amplitude limiting circuit 4 as an induced voltage signal. The amplitude limiting circuit 4 limits the amplitude level of the induced voltage signal to a positive-side load common one level to the center of its own amplitude. The limited induced voltage signal is inputted to a sample holding circuit 5, and sampled and held by a gate signal synchronizing with a commutation spike made to be contained in an induced voltage signal from a gate-signal generating circuit 6. An output from the circuit 5 is transmitted over a control circuit 3, and a semiconductor commutator device 1 is controlled by the control circuit 3.

Filed: 1984-11-09
Abstract: PURPOSE:To eliminate the ferromagnetic property at jointed places using a simple device by a method wherein, after each of non-magnetic steel is welded, the oxide formed on the surface of the welded place is removed. CONSTITUTION:The spool of a superconductive magnet, the case wherein the superconductive magnet is housed, and the non-magnetic steel plate material on which a structure such as the reinforcement member of the superconductive magnet and the like are abut-welded at the butt-together part on the end face in the air using a TIG welding device.

Abstract: PURPOSE:To perform correct charging operation at all times by judging the charged state of a battery at the charger side, stopping the charging operation or performing recharging operation, and exhibiting the charged state to a user by means of a charge indicating lamp. CONSTITUTION:When charging operation is started (t=0), it is carried out with initial charging current (I0=1.2A) and a charge indicating lamp lights to indicate the charging operation. Charging current I starts to decline at a time point (t=t1) when the battery voltage reaches to 14.7+ or -0.15V, and the time point (t=t2) when the charging current I declines below 0.2A is detected whereafter charging operation is carried out for 30min with a constant voltage. The charging operation is stopped for one min and the open voltage of the battery is measured. It is judged that the charging operation has finished if the measured open voltage is equal to or higher than 13.0+ or -0.15V, and constant voltage charging operation is further carried out for 120min with the charge indicating lamp consuming power thereafter the charging operation is stopped. By such method, overcharge due to long time charging operation can be prevented.
