TANDEM SERIES TANDEM SERIES DOUBLE DYNAMOMETERS IN-LINE Magtrol offers 3 types of dynamometer brakes to absorb load: Hysteresis (HD Series), Eddy-Current (WB Series) and Magnetic Powder (PB Series). Each type of Dynamometer has advantages and limitations and choosing the correct one will depend largely on the type of testing to be performed. With over 50 standard models to choose from, Magtrol Sales professionals are readily available to assist in selecting the proper Dynamometer to meet your testing needs. FEATURES ▪ 13 Models with Maximum Torque: 5 N·m ... 1 200 N·m (3.6 lb·ft... 885 lb·ft) ▪ Braking Power: 3 kW ... 140 kW ▪ Stable Braking Torque, without Shock ▪ Low Moment of Inertia ▪ Operating Direction CW / CCW ▪ Braking Torque Measurement Integrated ▪ Integrated Optical Speed Sensor ▪ Special designs available upon request DESCRIPTION Eddy-current Brake Dynamometers (WB Series) provide increasing torque as the speed increases, reaching peak torque at rated speed. They are ideal for applications requiring high speeds and also when operating in the middle to high power range. Powder Brake Dynamometers (PB Series) provide full torque at zero speed and are ideal for applications operating in the low to middle speed range or when operating in the middle to high torque range. Tandem Dynamometers are based on the combination of Eddy-current Dynamometers (WB  Series) and Powder Dynamometers (PB  Series) mounted in line on a common base and connected by an electromagnetic clutch. Both dynamometers are cooled by a water circulation system, which passes inside the stator to dissipate heat generated by the braking power, allowing a power rating up to 140 kW. Both WB and PB Dynamometers integrates a torque measurement system with accuracy ratings of ±  % to ±  % full 0.3  0.5  scale, depending on size and system configuration. APPLICATIONS Mounted on test benches, TANDEM Dynamometers allow performance and reliability testing on driving elements such as electric motors, servomotors, geared motors, reduction gears, pneumatic equipment, hydraulic transmission systems and starter motors. TANDEM OPERATING PRINCIPLES Because the characteristics of the WB and PB dynamometers are complementary, Magtrol is able to offer them mounted in a tandem setup. Each dynamometer (WB and PB) can autonomously operate according to its own characteristics (Please refer to specific data sheet). An electromagnetic clutch will automatically switches off at the maximum speed of the PB Powder Dynamometer and automatically switches on at zero speed. Once the system is working over the PB Powder Dynamometer speed limit, the clutch cannot be switched on before the system being at 0 rpm (no longer rotating). DUAL - DOUBLE WB DYNAMOMETER IN TANDEM OPTICAL SPEED SENSOR For application requiring higher power in a dedicated speed range, Magtrol offers some of the Eddy Current Dynamometer mounted in line on a common base. This would be for example the models 2 WB 65 + 2 WB 65 (rated torque 40 N·m, max  speed 24 000 rpm, max power 24 kW) or 2 WB 115 + 2 WB 115 (rated torque 200 N·m, max speed 15 000 rpm, max power 60 kW). Each TANDEM has an optical speed sensor delivered as standard. TANDEM  has an optical speed sensor with 43 30 PPR (Pulses Per Revolution); TANDEM 65, TANDEM 115 & TANDEM  has an optical speed sensor with a 60  15 PPR encoder.

TANDEM SERIES TANDEM CONFIGURATIONS The Dynamometers can be complemented by various electronic modules such as the DES Series (Power Supply), TSC 401 (Torque/Speed Conditioner) and DSP  7000 (High Speed Programmable Dynamometer Controller). accurate torque and speed measurement with high noise immunity. For a dynamic, high-precision system, the torque transducer can be mounted in line between the unit under test and the dynamometer, providing a torque accuracy of 0.1 %. Magtrol also offers In-Line Torque Transducers (TS  Series or TM  Series) or Torque Flange (TF Series) for extremely Computer...
