减速机技术资料：

电机有两大类：交流电机、直流电机。交流电机中用得最多的是异步电机（感应电机），转别是鼠笼式异步电机。现在伊诗图电气Eastour给大家介绍直流电机、交流电机调速方法。
直流电机调速方法：
直流电机是指将直流电送到直流电机，把直流电机的电能转换成机械能。这里首先要介绍如何将市电的交流电转换成需要的直流电。六十年代以前采用的是发电机－－电机系统（f-d），这种方法只有在电机由专用的发电机供电时才有可能。另一种是可控硅－－电机系统（scr-d）。
直流电机的调速还比较方便，可以通过调节电枢供电电压，电枢中串联电阻，激磁回路串联电阻来实现。
可见直流电机调速有三种方法，而且调节电枢供电电压的方法容易实现平滑、无级、宽范围、低损耗的要求。直流电动机电磁转矩中的两个可控参量和是互相独立的，可以非常方便地分别调节，这种机理使直流电动机具有良好的转矩控制特性，从而有优良的转速调节性能。
尽管直流电机调速就其性能而言，可以相当满意，但因其结构夏杂，惯量大，维护麻烦，不适宜在恶劣环境中运行，不易实现大容量化、高压化、高速化，而且价格昂贵。
交流电机调速方法：
交流电机刚好相反。交流电机结构简单、惯量小、维护方便，可在恶劣环境中运行，容易实现大容量化、高压化、高速化，而且价格低廉。
从节能的角度看，交流电机的调速装置可以分为高效调速装置和低效调速装置两大类。高效调速装置的特点是：调速时基本保持额定转差，不增加转差损耗，或可以将转差动率回馈至电网。
低效调速装置的特点是：调速时改变转差，增加转差损耗。
高效调速方法包括：改变极对数调速—鼠笼式电机变频调速—鼠笼式电机串级调速—绕线式电机换向器电机调速—同步电机。
低效调速方法包括：定子调压调速—鼠笼式电机电磁滑差离合器调速—鼠笼式电机转子串电阻调速—绕线式电机。
伊诗图电气Eastour专业销售感应电机、调速电机、可逆电机、电磁制动电机、力矩电机、小型齿轮减速电机、直流有刷电机、直流无刷电机、行星减速机等。

直流电机励磁方式:
他励直流电机
励磁绕组与电枢绕组无联接关系，而由其他直流电源对励磁绕组供电的直流电机称为他励直流电机，永磁直流电机也可看作他励或自激直流电机，一般直接称作励磁方式为永磁。
并励直流电机
并励直流电机的励磁绕组与电枢绕组相并联，作为并励发电机来说，是电机本身发出来的端电压为励磁绕组供电；作为并励电动机来说，励磁绕组与电枢共用同一电源，从性能上讲与他励直流电动机相同。
串励直流电机
串励直流电机的励磁绕组与电枢绕组串联后，再接于直流电源。这种直流电机的励磁电流就是电枢电流。
复励直流电机
复励直流电机有并励和串励两个励磁绕组。若串励绕组产生的磁通势与并励绕组产生的磁通势方向相同称为积复励。若两个磁通势方向相反，则称为差复励。
