电动机与发电机你知道有什么不一样的吗?

来源:http://www.jnmcd.com 发布时间:2018-12-28 浏览:
电动机与发电机原理底子相同,分别在能量转化的方向不一样,发电机是借由负载(如水力、风力)将机械能、动能转为电能,若没有负载,发电机不会有电流流出。
Motors and generators have the same principle base, and the direction of energy conversion is different. Generators use loads (such as hydraulic and wind) to convert mechanical energy and kinetic energy into electricity. Without loads, generators will not have current outflow.
电动机和电力电子、微控器合作已构成一新学门,称为电动机控制。 在运用微型马达前需先了解其运用的电源是直流电仍是交流电,如果是交流电,还需知道它是三相仍是单相的交流电,接错电源会致使不必要的损失和危险。
Motor and power electronics, micro-controller cooperation has formed a new door, known as motor control. Before using the micro motor, it is necessary to know whether the power supply used is DC or AC. If AC is AC, it is also necessary to know that it is three-phase or single-phase AC. Connecting the wrong power supply will cause unnecessary loss and danger.
马达翻滚后若没有接负载或负载很轻使得马达转速快,则感应电动势较强,此时马达两端电压为,电源供给电压减去感应电压,因此电流削弱。
If the motor is not loaded or the load is very light after rolling, which makes the speed of the motor fast, the induction electromotive force is stronger. At this time, the voltage at both ends of the motor is the supply voltage of the power supply minus the induction voltage, so the current is weakened.
若马达的负载很重,转速慢则相对感应电动势较小,也因此电源需供给较大电流(功率)以对应所需的较大功率来输出/作功。
If the load of the motor is heavy and the speed is slow, the relative induction electromotive force is small, so the power supply needs to supply a larger current (power) to output/work with the corresponding higher power.
输出:指马达在单位时间内可进行的作业,并依马达的作业速度及转矩来抉择。 额定输出:马达在额定电压,额定频率下能体现其最优异特性,并一起连续发作的各种能量输出,如作业速度或转矩等数值。一般微型马达铭牌上会标明额定输出之数值。亚洲一般以瓦特(W)为单位,欧美则运用马力(HP)。
Output: refers to the operation of motor in unit time, and according to the speed and torque of motor operation to choose. Rated output: The motor can show its best performance at rated voltage and frequency, and can generate various energy outputs continuously together, such as operating speed or torque. Normally, the nominal output value will be marked on the nameplate of micro motor. Asia is generally based on Watt (W), while Europe and the United States use horsepower (HP).

额定功率(容量):额定输出之功率(瓦特)。 马力:马达输出功率的单位之一为马力(Horse power,简称HP),1马力(HP)=746瓦特(Watts)额定电压:运用时所能容许的输入电压,运用逾越此额定电压时,一般马达仍可作业,但其电容器之运用寿命会明显缩短,甚至耐久作业后发作高热而焚毁。
Rated Power (Capacity): Rated Output Power (Watt). Horse power: One of the units of motor output power is horsepower (HP), 1 horsepower (HP) = 746 watts (Watts) rated voltage: the input voltage that can be allowed in operation, when applied beyond this rated voltage, the general motor can still operate, but the service life of its capacitor will be significantly shortened, and even burned up after long-term operation.
运用单位以V(伏特)标明。 转矩 发动转矩:指马达请动时瞬间发作的转矩,马达若受比此一转矩更大的抵触抑止负载,则马达将无法发动。也称为开端转矩。
The unit of use is marked by V (volt). Torque starting torque: refers to the moment when the motor starts to move. If the motor is restrained by a greater resistance than this torque, the motor will not be able to start. Also known as starting torque.
中止转矩:指马达在必定电压、必定频率下所能输出之最大转矩,一旦所承载之负载逾越此转矩规划,马达随即中止。
Stop Torque: refers to the maximum output torque of the motor at a certain voltage and frequency. Once the load exceeds the torque planning, the motor stops immediately.
额定转矩:指马达在额定电压、额定频率下可连续发作额定输出时的转矩。即为额定作业速度时候所发作的转矩。
Rated Torque: refers to the motor at rated voltage, rated frequency can be continuously rated output when the torque. That is, the torque occurring at rated operating speed.
转速额定作业速度:指马达做额定输出时的作业速度,为马达在无故障下运用之理想的作业速度。
Speed Rated Operation Speed: refers to the operation speed of motor at rated output, which is the ideal operation speed for motor in trouble-free operation.
无附载作业速度:指马达在无负载状态下的作业速度。
No-load operation speed: refers to the operation speed of motor under no-load condition.
CW/CCW:指马达的作业方向。CW为从出力轴端看之顺时针方向,而CCW则为逆时针方向之作业。
CW/CCW: refers to the direction of motor operation. CW is clockwise from the output shaft end, while CCW is counterclockwise.
