5502/5503 – Manual Dynamometer Switch Box
Product Description
Magtrol Models 5502 and 5503 are manually-operated switch boxes that permit the connection of up to three Magtrol Dynamometers to a single Dynamometer Controller. Use of the switch boxes facilitates quick and easy interfacing to multiple dynamometers without the need to disconnect and reconnect the brake and control cables. For Magtrol WB Eddy-current or PB Powder Brake Dynamometers, BOTH a 5502 AND a 5503 Switch Box are necessary. Magtrol HD or ED Hysteresis Dynamometers only require the 5502.

[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] => Test from a stationary position or move a dynamometer to alternate testing stations with ease with Magtrol's Dynamometer Table. The stand is designed from lightweight aluminum with casters for smooth mobility, and is sturdy enough to support even the heaviest of Magtrol dynamometers. The design can be retrofitted to any Magtrol dynamometer and is easily reconfigured for added versatility.

[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.
