Applications
In the laboratory, the DSP7010’s high sample rate provides superior resolution for data acquisition and curve plotting. This allows capturing more usable motor test data during switching, breakdown and other transitional areas of the motor test curve. For production and incoming inspection, the DSP7010 displays torque, speed and power at all times, allowing the Controller to be used as a manual stand-alone unit or as part of a complete PC system.

[post_content] => The Powder Brake Dynamometer (PB Series) contains, as its name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction. They are ideal for applications operating in the low to middle speed range or when operating in the middle to high torque range. Like Hysteresis Brakes, Powder Brakes provide full torque at zero speed. Like the Eddy-Current Brake Dynamometers, the PB series are water-cooled, allowing for power ratings up to 48 kW. The PB Dynamometers have accuracy ratings of ± 0.3% to 0.5% full scale, depending on size and system configuration.
Features
- 9 Models with Maximum Torque from 5 N·m to 1 200 N·m (3.69 lb·ft to 885 lb·ft)
- Braking Power: 500 W to 48 kW
- Stable Braking Torque
- Low Moment of Inertia
- Operation in Either Rotational Direction
- Braking Torque Measurement Integrated
- Integrated Optical Speed Sensor
- Special designs available upon request
Operating Principles
The PB Series - Powder Dynamometers contain, as their name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction between rotor and stator. The Powder Dynamometers (PB) produce their rated torque at zero speed. The element to be tested can be loaded at standstill to determine the starting torque.
Optical Speed Sensor
Each PB Series Dynamometer has a standard optical speed sensor. PB 43 has an optical speed sensor with a 30 PPR (Pulses Per Revolution); PB 65, PB 115 & PB 15 has an optical speed sensor with a 60 PPR. For higher speed resolution in low speed applications, Magtrol offers a 600 PPR or 6 000 PPR encoder as an option.

[post_content] => The Remote Switch Box is used in conjunction with the TAB 825 Series Dynamometer Tables to control the on/off function of the blowers. It is typically attached to the underside of the table and provides a convenient method for powering the blowers on & off. Originally designed for use with 120 Vac blowers, the RSB can be configured for use at 220 Vac (contact Magtrol).

[post_content] => The TCBS Thermocouple Connection Barrier Strip provides a method of connection the data acquisition device, which is usually installed in the main console, to the device being monitored up to 3 meters away. All eight thermocouples pairs are bundled into a single cable and terminated in a die cast aluminum box with barrier strip jackets for easy connection.
Interconnection errors can be avoided by using the barrier strip with the relevant thermocouple extension or compensation material. The strips are marked to identify the alloy and polarity.
The box can be supplied with optional T-nuts for easy mounting to a
T-slot table or
Magtrol PT 25 Base Plate.

[post_content] => The PC-150 Polarity Changer uses Magtrol’s M-TEST 7 Software to remotely switch the polarity of a DC power supply in order to reverse the direction of the motor under test. When switching polarity, the voltage sense lines will also change in order to maintain the proper polarity on the power supply sense terminals.
