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] => If currents continuously reach above 20 amps, an external sensor must be used. Magtrol offers three different types of external shunts for use with Magtrol Power Analyzers. The HA Series shunt, designed for power cable hook-up utilizing 3/8-16 screws, has an insulating base and can be mounted on conductive surfaces. The LAB Series shunt also comes with an insulating base, along with thumb screws for the power leads and knurled nuts on the sensing terminals. The FL Series is a relatively small bus, bar-mounted shunt with large end blocks. The comparatively large end blocks and short spacing aid in cooling and allow the shunt to operate in more extreme environments. All shunts are calibrated on equipment with current certifications traceable to N.I.S.T.

[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’s AMF Series Adjustable Motor Fixtures are used to secure small to medium-sized motors in place while running any test. These extremely versatile fixtures also enable easy motor centering for coupling to a Magtrol
HD Series Hysteresis Dynamometer. (Couplings can be supplied upon request.) Various motor lengths are accommodated by either an attached T-slotted base plate or sliding base, depending on the model.
The AMF-1, -2 and -3 Fixtures feature one or two adjustable bridges, each fitted with a fluted knob clamp screw, to allow clamping anywhere along the axis of the motor. The adjustable bridge on the AMF-V Fixture incorporates a straight-line action clamp with a V-angle rubber padded clamp to maximize the mounting area.
To safeguard the motor, locking thumb screws provide protection against vibration and all motor-to-fixture contact surfaces are nylon padded for scratch-free clamping.

[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.
