介绍空心杯电机的技术信息

### 空心杯有刷电机特点：

无齿槽效应  
结构严谨，体积小  
能量转换高效  
多级换向片，降低转矩波动  
转动惯量低伺服特性好  
灵活搭配减速机、编码器  
线性参数特性关系突出

### TDC空心杯有刷电机绕组形式：

大功率片式阵列绕组  
小功率层叠式绕组  
以上两种形式的绕组可以根据参数需求不同进行选择，漆包线的线径与匝数遵守以下特性

### 相间阻抗小：

绕组线径大，绕组匝数少  
启动电流大  
转速常数高（KV值高）

### 相间阻抗大：

绕组线径小，绕组匝数多  
启动电流小  
转速常熟低

### TDC空心杯有刷电机使用寿命：

通常情况下，电机的使用寿命与电机的工作，环境有很大的影响，在良好的环境下电机工作的寿命要比恶劣的环境下长，一般我们的电机寿命可以达到1000小时左右

### 寿命影响因素

1. 转速高刷组的机械磨损远大
2. 工作方式启/停频率高或者正/反转切换
3. 负荷电流负荷越大，磨损越大
4. 环境粉尘，温/湿度，震动，安装方式都会对寿命产生影响
 
### TDC空心杯无刷电机特点：

使用寿命长，高效率，在合理的设计下无齿槽效应，伺服性良好，过载能力强，功率密度高，可在高温环境下运行，采用烧结钕铁硼强磁

### TBC空心杯无刷电机绕组形式与空心杯有刷电机绕组形式相同TBC-4极系列特点：

转子采用2对极，具有超强功率密度真正做到小体积大功率绕组采用片式阵列方式 高转速，大扭矩输出 启动响应速度快

### TBC系列分类：

开关锁存型霍尔传感器 线性霍尔传感器（可以配置线性霍尔驱动器）无霍尔传感器 内部集成驱动器 高温医疗灭菌

### TBC使用寿命：

TBC空心杯无刷电机，在配合NMB滚珠轴承的情况下寿命可高达几万小时，使用寿命受高转速，动平衡振动与轴承的载荷影响
