Product Description
Magtrol’s SBB15 Signal Breakout Box is designed to assist in the monitoring of speed, torque, and index signals obtained from either a Magtrol dynamometer or torque transducer. The easy-to-use SBB15 is simply inserted in series between a Magtrol controller and any Magtrol dynamometer or torque transducer. Connections are made via D-Sub 15 signal cables.
Speed, torque, and index signals are outputted through BNC connectors to an oscilloscope or other DAQ instrumentation device. Switching to the external encoder will switch the Tach A, Tach B, and Index signals, while the Torque signal will still be passed through from the dynamometer or torque transducer. The SBB15 Signal Breakout Box is a convenient and reliable accessory that reduces the necessary wiring required for signal monitoring.
Features
- Two D-Sub 15 Connectors: provides an in-line connection between a Magtrol DSP Controller and a dynamometer or a torque transducer
- Four BNC Connectors: provides easy access to Tach A, Tach B, Torque, and Index signals for connecting to an oscilloscope or other data acquisition (DAQ) device
- Sturdy Assembly: packaged in an extruded aluminum case with metal mounting flanges
- An external encoder input is provided for connecting high resolution encoders
- A slide switch allows switching between a torque transducer and an external encoder

[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.

[post_content] => Hysteresis Brake Dynamometers (HD Series) are versatile and ideal for testing in the low to medium power range (maximum 14 kW intermittent duty). With a Hysteresis Braking system, the Dynamometers do not require speed to create torque, and therefore can provide a full motor ramp from free-run to locked rotor. Brake cooling is provided by convection (no external source), by compressed air or by dedicated blower, depending on the model. All Magtrol Hysteresis Dynamometers have accuracy ratings of ± 0.25% full scale — depending on size and system configuration.
Features
- 16 Standard Models with Maximum Torque from 2.5 oz·in to 500 lb·in (18 mN·m to 56.5 N·m)
- Hysteresis Braking System: Provides precise torque loading independent of shaft speed
- Motor Testing from No Load to Locked Rotor
- Accuracy: ±0.25% (Full Scale)
- Air Flow Sensor: For protection against overheating and operator error
- Standard Torque Units: English, Metric and SI
- Custom Dynamometers: for special torque and speed requirements
- Easy Calibration
The Hysteresis Braking System
All Magtrol Hysteresis Dynamometers absorb power with a unique Hysteresis Braking System which provides frictionless torque loading independent of shaft speed. The Hysteresis Brake provides torque by the use of two basic components - a reticulated pole structure and a specialty steel rotor/shaft assembly - fitted together but not in physical contact. Until the pole structure is energized, the drag cup can spin freely on its shaft bearings. When a magnetizing force from the field coil is applied to the pole structure, the air gap becomes a flux field and the rotor is magnetically restrained, providing a braking action between the pole structure and rotor.

[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.

[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.
