Only one-way operation of the automatic control circuit of the motor
In certain applications, it is crucial to allow a motor to operate in only one specific direction, even when the power supply phase sequence is incorrect. This situation may arise due to external factors, such as incorrect wiring after maintenance....
5-motor hexapod circuit
This circuit has a long history, originating from an idea by Rich Piotter and later refined by Wilf Rigter and Bruce Robinson. The final result does not include the necessary motor drivers, which are typically H-bridge based, but presents a...
R-C Twin-Tee Circuit Reduces Power-Supply Hum
The R-C twin-tee passive circuit provides band-reject (notch) filtering suitable for portable applications. It has a loaded circuit Q of 0.25. Effective rejection is achievable when the bridge is balanced, which requires close tolerances of the adjustable components, and the...
Motor control with tachometer
The generator output is rectified, filtered, and applied between the positive supply voltage and the base of the detector transistor. This configuration provides a negative voltage that reduces the base voltage as the speed increases. During normal operation, if the...
motor timer
The primary concept is to rotate the motor slightly every 15 seconds. A monofilament line conveys the motion to the ornament, which is wound by the motor and gradually unwinds as the ornament turns. The charging circuit includes a 1...
Three motor control circuit start and stop sequence requirements
The circuit shown in Figure 3-89 illustrates a system where starting motor M1 allows motors M2 and M3 to initiate operation. Upon shutdown, motor Mz can be stopped first; however, once motor M1 is stopped (by pressing switch SB2), motors...
Dual-Motor SIP&PUFF Controlled Kayak System
The YouTube video below demonstrates the quick and easy setup of the system at the launch site.
The provided description indicates a focus on the efficiency of system installation at a launch site, as showcased in a YouTube video. In an...
Two-speed motor stator winding 2Y-2Y connection
As illustrated in Figure 3-105, this diagram depicts the lead wiring configuration for a two-speed motor stator with a 2Y/2Y connection.
The two-speed motor stator wiring diagram is essential for understanding the configuration and operation of the motor. In this setup,...
Dynamic noise reduction with DC volume control
A dynamic noise reduction circuit and a DC volume and tone balance control circuit, which are applied to the input stage and the discharge line between the amplifier.
The described circuit configuration incorporates two primary functions: dynamic noise reduction and volume/tone...
