[post_content] => Magtrol’s EMA Series Stand Alone Encoder provides a squarewave output on two channels for up/down counting or free-runmotor speed measurement applications. Each channel outputs the specified pulses per revolution of the encoder shaft, and is 90° phase-shifted in order to determine direction when used with the appropriate counter/timer DAQ board. The device incorporates an infrared optical switch and disk assembled into a rugged aluminum housing. The encoder is supplied with an 8 mm rectangular key for easy alignment to a Magtrol PT 25 Base Plate.

[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] => Magtrol offers these calibration beam assemblies and weights for calibrating
HD-Series Hysteresis Dynamometers. To perform a successful dynamometer calibration, precision weights heavy enough to apply a torque at or close to the full scale rating are required. Magtrol WT Series Calibration Weights are equal to the dynamometer's torque value, divided by the distance between the outer pin and centerline of the corresponding CB Series Calibration Beam. Calibration Weights are available in English or SI units. Calibration Beams are marked for both English and SI weights. For detailed dimension drawings, click on the model's underlined link. A PDF document will open in a new window.(Adobe Acrobat Reader 7.0, or later, is required.)

[post_content] => The Model 5241 is a voltage-controlled power amplifier designed exclusively for Magtrol's Model HD-825 Hysteresis Dynamometer. Because of its double braking system, the HD-825 requires more than 4 amps of power in order to reach full torque. The 5241 (which can provide up to 5 amps of output current) is necessary in order to amplify the power between a
6200 or
DSP7000 Controller (which both have a maximum current output of 1 amp) and the HD-825 Dynamometer.
