To adjust speed, the conventional speed control method raises the applied voltage of the motor when speed is slower than the setting speed, and lowers the applied voltage when speed is faster than the setting speed. Control Technologies of Deceleration Torque (Electromagnetic Brake Type) 3.3.1. Due to the single-phase AC voltage, it cannot detect rotation directions (Refer to Figure 7).ģ.3. This is converted to pulse signals to detect motor speed. A tachogenerator generates a 12-cycle sinusoidal wave single-phase AC voltage per 1 rotation. Closed Loop Control Technologies of the DSC SeriesĪn AC speed control motor is equipped with a tachogenerator for speed detection. This combination achieves improvements such as equipment downsizing and reliability. This series employs the KII Series motor and gearhead, which offer excellent permissible torque and strength. While being locked, all setting operations are disabled and thus, incorrect operations such as accidentally rewriting or deleting data can be avoided.Ħ) Combination of Highly Reliable Motor and Gearhead The data editing can be locked by holding the MODE key on the operating panel. Function to put a Limit on Speed Setting RangeĪn unintended speed setting operation can be avoided by using the "Speed Upper and Lower Limit" parameter to put a limit on the speed setting range in advance.During a parallel-motor operation when each motor has speed difference, the speed difference can be easily adjusted with the "External Speed Command Off-Set" parameter. With a single external speed command, up to 20 motors can be operated in parallel. Function to Easily Adjust Speed Difference.This article introduces the features and control technologies of the DSC Series. These motors have been used as power sources for various kinds of industrial devices. For the past 40 years, Oriental Motor has developed a multitude of AC speed control motors while meeting the needs of the market. IntroductionĪn "AC motor and speed controller package" is a packaged product consisted of a robust AC motor and a compact, low noise, and long life speed controller (1), allowing stable speed control while changing the applied voltage to the induction motor with the phase control system. This article describes the features and new control technology of the DSC Series. The new DSC control technology also accomplishes two functions that conventional products cannot instant reversal of single phase induction motors, and vertical drive by deceleration control (electromagnetic brake type only). In order to improve ease of use, this product is equipped with an operation panel for monitoring various functions, as well as for digital settings. The DSC Series is a new AC Speed Control product. The software is simple and easy to operate.Download PDF Features and Control Technologies of the DSC Series Motor and Speed Controller PackageĪn "AC motor and speed controller package" is a unit product composed of a robust, single-phase induction motor, and a low noise, long life speed controller. At the same time, a protective gas input is added.Ħ. Automatically switch the two-way atmosphere flow, fast switching speed and short stabilization time. Digital flow meter, air flow control is more precise.ĥ. USB communication interface, strong versatility, reliable and uninterrupted communication, supports self-recovery connection function.Ĥ. The sensor is closely integrated with the furnace body to make the baseline more stable, and the sensitivity and resolution are greatly improved.ģ. Temperature control methods: heating, constant temperature (automatic program control)Ītmosphere control gas: nitrogen, oxygen (the instrument automatically switches)ĭisplay mode: 8-inch LCD touch screen display, super hardness instrument mask design.ġ.Industrial-grade 8-inch touch screen, the instrument face frame is perfectly combined with touch screen.Ģ. Temperature range: room temperature-500 degreeĬonstant temperature time: recommended <24h GB/T 19466.6-2004/ISO 11357-3:1999 Part 6 : Determination of oxidation induction time(iso thermal OIT) and oxidation induction temperature(dynamic OIT). GB/T 19466.3-2004/ISO 11357-3:1999 Part 3 : Determination of temperature and enthalpy of melting and crystallization. GB/T 19466.2-2004/ISO 11357-3:1999 Part 2 : Determination of glass transition temperature and glass transition stepheight. It can measure the melting point of melting, block, particles, film, pipe, sleeve, ect for various plastics. The differential scanning calorimeter is the type of touch screen, which is mainly customized for the plastic industry. DSC Touch Screen Differential Scanning Calorimeter DH-DSC-510C
