Abstract: A cycloid speed reducer includes two rotating disc assemblies. Each rotating disc assembly includes two cycloid discs. In other words, the cycloid speed reducer has four cycloid discs to be contacted with the corresponding rollers. Consequently, the load withstood by each cycloid disc is reduced. Since the cycloid speed reducer has stronger structural strength, the cycloid speed reducer can be applied to the high-load circumstance. Moreover, an eccentric assembly of the eccentric device includes plural eccentric cylinders. The eccentric cylinders are installed within the axle holes of the corresponding cycloid discs. Due to the plural eccentric cylinders, the eccentric direction of two cycloid discs is opposite to the eccentric direction of the other two cycloid discs. Consequently, it is not necessary to install an additional weight compensation device in the cycloid speed reducer to compensate the dynamic equilibrium.

Abstract: A motor driven linear actuator comprises an electric motor, a ballscrew device, and a rolling bearing. The electric motor includes a motor shaft having a first end portion. The first end portion includes an end surface and a receptacle having a first accommodation space. The ballscrew device includes a screw having a first end portion coaxially connected to the first end portion of the motor shaft. The first end portion of the screw includes a first section to be accommodated in the first accommodation space for fixing the screw with the motor shaft. The rolling bearing is disposed between the electric motor and the ballscrew device for supporting the first end portion of the screw. The end surface of the motor shaft contacts and abuts against the rolling bearing for limiting the movement of the rolling bearing between the electric motor and the ballscrew device.

Abstract: The present disclosure provides an ultrasonic drive and driving method configured for driving an ultrasonic tool. The ultrasonic drive includes a switch module, a sensing element and a control element. The sensing element senses the voltage and current of the ultrasonic tool and generates a sensing signal accordingly. The control element receives the sensing signal and outputs a control signal. The switch module outputs an ultrasonic signal according to the control signal for controlling the vibration of the ultrasonic tool. When the ultrasonic drive operates a frequency sweep function, the control element determines an operating interval and an operating frequency of the ultrasonic signal. When the ultrasonic drive operates a frequency following function, the control element adjusts the operating frequency according to the sensing signal for keeping the impedance of the ultrasonic tool consistent.

Abstract: An axial flux machine includes a modulated stator, a rotor, and a plurality of spacers. The modulated stator includes plural stator units. Each stator unit includes a magnetic core and at least one winding. The magnetic core has first plate, a second plate, and a sidewall connecting the first plate to the second plate, and the winding is disposed on the magnetic core. The stator units construct the modulated stator. By modulating the stator, the slot fill factor and the cogging torque performance can be improved. The spacers are disposed to isolate the magnetic cores. The rotor is disposed in the modulated stator and includes plural first magnetic pieces and second magnetic pieces arranged alternately, and the magnetic flux lines of the first and second magnetic pieces respectively pass through sidewalls of the magnetic cores to construct C-type magnetic loops of opposite directions thereby improving power density.
