[post_content] => Eddy-Current Brake Dynamometers (WB Series) are ideal for applications requiring high speeds and also when operating in the middle to high power range. Eddy-Current Brakes provide increasing torque as the speed increases, reaching peak torque at rated speed. The dynamometers have low inertia as a result of small rotor diameter. Brake cooling is provided by a water circulation system, which passes inside the stator to dissipate heat generated by the braking power, providing high continuous power ratings (max. 140 kW). WB Series Dynamometers integrate a torque measuring system with accuracy ratings of ± 0.3 % to ± 0.5 % full scale, depending on size and system configuration.
Features
- 12 Models with Maximum Torque from 400 mN·m to 560 N·m (56.6 oz·in to 413 lb·ft)
- Braking Power: from 500 W to 140 kW
- Stable Braking Torque, without Shock
- Low Moment of Inertia
- Low Residual Torque
- Operating Direction CW / CCW
- Braking Torque Measurement Integrated
- High Rotational Speed (≤ 80 000)
- Integrated Optical Speed Sensor
- Special designs available upon request
Operating Principles
The WB Eddy-Current Dynamometers develop their full power at high rotation speeds. The WB Series is particularly intended for motors which rotate at high speeds, up to 80 000 rpm (up to 100 000 rpm with
WB 23 / 27; see specific datasheet). The braking torque depends on the rotation speed.
Optical Speed Sensor
Each WB Series Dynamometer is equipped with an optical speed sensor.
WB 32 is equipped with a 4 PPR (Pulses Per Revolution) encoder, WB 43 and WB 65 HS are equipped with a 30 PPR encoder; WB 65, WB 115 & WB 15 are equipped with a 60 PPR encoder.

[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] => Magtrol Coupling Guards are easily removable and designed to mount in front of Magtrol HD Series Dynamometers. They are also available for some WB Series Dynamometers.
Coupling Guards help keep objects from vertical interference and aid in preventing accidental coupling contact during rotation. The guard length required will change according to the coupling size used with the dynamometer.
Magtrol Coupling Guards are not explosion proof and are not intended as protection against catastrophic coupling failure.

[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.
