磁滞测功机

原理：   磁滞测功机是由带齿极定子、空心磁滞杯转子、激磁线圈、底板等组成，当磁滞测功机内部线圈通过电流时则产生磁力线，并形成磁回路而产生转矩，改变激磁电流即可改变测功机滞动转矩从而达到控制负载转矩的目的完成对负载特性的测试.   特点： 1、转子为空心杯形结构，适用于低速和中高速电机 2、测试精度高，灵敏度高，负载转矩稳定性和测试重复性好 3、无电刷滑环结构，气隙中无磁粉摩擦,使用寿命超长 适用：   适用于中小功率电机的型式试验，如起动电机恒力矩带载起动、异步电动机、小功率直流电机、串激电机及电动工具行业等.尤其适合于测试各种微特电机的动态特性曲线。 磁滞测功机（自然冷却型） 型号 Type 测试范围Testing Range 运行功率Power(W) 转矩Torque(N.m) 转速Speed(rpm) 连续Continual Operation 短时Shorttime Operation ZC01KB ≤0.01 ≤30000 ≤10 ≤30 ZC02KB ≤0.02 ≤30000 ≤10 ≤40 ZC05KB ≤0.05 ≤30000 ≤20 ≤80 ZC1KB ≤0.1 ≤25000 ≤40 ≤100 ZC2KB ≤0.2 ≤25000 ≤60 ≤150 ZC5KB ≤0.5 ≤20000 ≤100 ≤300 ZC10KB ≤1 ≤15000 ≤200 ≤600 ZC20KB ≤2 ≤15000 ≤250 ≤800 ZC50KB ≤5 ≤8000 ≤400 ≤1500 ZC100KB ≤10 ≤6000 ≤600 ≤2000 ZC150KB ≤15 ≤6000 ≤600 ≤2000 ZC200KB ≤20 ≤4000 ≤1200 ≤6000 表1   磁滞测功机（自然冷却型） 型号 Type 测试范围Testing Range 运行功率Power(W) 转矩Torque(N.m) 转速Speed(rpm) 连续Continual Operation 短时Shorttime Operation ZC20KC（水冷） ≤2 ≤15000 ≤500 ≤1000 ZC50KC（水冷） ≤50 ≤8000 ≤1000 ≤2000 ZC100KC（水冷） ≤10 ≤6000 ≤1500 ≤3000 ZC150KC（水冷） ≤15 ≤6000 ≤1500 ≤3000 ZC200KC（水冷） ≤20 ≤4000 ≤2000 ≤6000 Hysteresis Dynamometer with a tooth from the stator pole, hollow hysteresis cup rotor, magnetizing coil, floor etc., when the hysteresis dynamometer within the coil currents are generated by magnetic field lines, and the formation of magnetic loop generated torque, change magnetizing current can change the dynamic hysteresis dynamometer torque so as to achieve the purpose of controlling the load torque load characteristics to complete the test.
