5242 – Power Amplifier

Product Description

The Model 5242 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 5242 (which can provide up to 5 amps of output current) is necessary in order to amplify the power between the DSP7010 Controller (which has a maximum current output of 1 amp) and the HD-825 Dynamometer.

Ordering Information

If the HD-825 is purchased without a dynamometer controller, please inform Magtrol of your controller model—as it may be necessary to modify your existing controller so that it functions properly with the 5242 Power Amplifier.

                    [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.

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.
