一般特征
BA系列
BA系列由三相，异步制动电机完全封闭式风扇冷却（TEFC）。BA系列范围从71开始
最多280帧尺寸。电源故障的电机制动器。制动动作始终通过非常快
在无意的电源故障的情况下，精确停止确保安全和提示。制动扭矩保持不变
in both directions of rotation and the motor brakes without shaft axial sliding. As standard the brake is AC 3-phase voltage supply
具有在单个终端板中连接的制动引线，同时应要求提供单独提供制动器
with a second terminal board or to have a DC brake supply with a built-in rectifier fitted inside the terminal box. The rectifier is
提供过电压和无线电频率排放保护装置。BA系列电机容忍高度过载速率和
are capable of withstanding overheating so as to guarantee the best reliability even under tough operating conditions. All MGM
series motors have been designed to be controlled by inverters. The motor winding insulation is class F, while class H is available
根据要求。电机结构型完全封闭外部冷却和IP54机箱（IP55和IP56可应要求提供）。
电机up to 132 frame size are fitted as standard with a hexagonal hole on the shaft at the non drive end to allow manual rotation,
即使电源关闭。所有BA系列电机都配有手工制动释放螺钉标准。
BA series brake disc has a large lining surface that allows high brake torque, low disc wear and consequently low maintenance
成本。制动扭矩可以通过拧紧一些螺母来容易地调节到所需的值。由于其特殊建筑
the brake friction surface is self-ventilated on the motor side, permitting a high brake workload and keeping brake time constant.
制动衬片材料是无石棉。
BA series motor frame is made of die cast, light metal on motors up to 132 size and the terminal board box, provided with cable
glands and plugs, is positioned 180
°
在电机支撑脚上。框架由铸铁从160帧尺寸开始制成
并且接线盒位于右侧（驱动端视图）。屏蔽和法兰由铝制电机制成，高达90
框架尺寸，以及100框架尺寸和上述电机上的铸铁。标准脚是集成的框架（它们不仅仅是
连接到框架上）在IM B3安装（脚安装）上，使电机非常坚固。此功能对这些功能非常重要
在开始和停止期间电动机强调的应用。
The brake friction surfaces are made of cast iron as a standard. The brake moving element and the brake coil have a laminated
核以减少电损耗并确保非常快速的制动干预。
BA系列主要特点是其坚固的结构，快速制动动作，恒定的制动时间，允许的较高
start/stop cycles also under severe applications, easily adjustable brake torque, low maintenance costs.
