Digital Dynamometer and Load Control Instrument Model 4600

The Model 4600 Dynamometer and Load Control Instrument, which operates with the Model 4610 line of low inertia load brake test heads, is primarily used for testing stepper motors and features both manual and automatic load control.

When used in the automatic mode, the ramp control will increase the current to the load brake at the rate and level pre-set by the two front panel controls.

When testing small stepper motors, pullout torque is easily measured. The operator first pre-sets the load brake level and ramp rate. Then, by depressing the Stall button, the load will ramp to the stall point of the motor, and the digital display will show the stall torque. Pullout torque is displayed by depressing the Peak button, therefore showing the peak torque at which the motor pulled out of synchronization.

The Model 4600 instrument functions with all Vibrac Transducers.

A front panel unit selection switch allows the display to be switched to oz-in, lb-in, Newton-centimeters, or % of full scale.

A 0-10 volt DC analog output is provided on the rear panel for use with an analog/digital conversion card for importing data to a PC or laptop.

The complete system (instrument and test head) is accurate to 1% of full scale.

Readout Instrumentation

FRONT PANEL DESCRIPTION

POWER — System power switch.

TORQUE SET CONTROL — The ten-turn potentiometer is for setting torque load.

RESET — The lighted push-button switch, when engaged, will reset the peak holding circuits.

HOLD — The lighted push-button switch, when engaged, will HOLD or LOCK the digital torque display.

PEAK — The lighted push-button switch, when engaged, will display peak torque from the internal holding circuits on the torque display.

ZERO ADJUST — For setting the proper zeroing voltage for the transducer that is connected to the instrument.

TORQUE READOUT — The 4-1/2 digit readout is scaled to read torque in direct engineering units or in percent full scale.

TRANSDUCER SELECTOR — The thumb wheel switch is for selecting corresponding transducer heads for use with this instrument and for selecting the engineering units to be displayed on the Torque Readout (English and Metric units).

TORQUE — The lighted push-button switch, when engaged, activates the torque set control.

OFF — The lighted push-button switch, when engaged, removes power from the load device on the test head.

STALL — The lighted push-button switch, when engaged, will apply full load to the device under test.

RAMP RATE CONTROL — The potentiometer is for setting the rate at which the load brake voltage is applied to the load (both torque and stall).
