GENTEQ
760-ECM Motor Speed Controller
The 760-ECM motor speed controller
is designed to provide manually
adjustable proportional speed
control for all sizes and voltages
of ECM DC Brushless motors.
Manual speed control is
accomplished by adjusting the
control pot in the clock-wise
direction to increase motor speed.
Adjusting the pot in the counter
clockwise direction will slow down
and eventually stop the motor as
the PWM signal is removed.
The 760-ECM is line voltage
independent and requires only a
24VAC supply. This unit is fully
enclosed and can be mounted in standard electrical boxes.
Variable speed control is accomplished via a Pulse Width Modulated
(PWM) output signal. The PWM signal operates at a nominal
13.5VDC at 80Hz and is capable of sourcing up to 5mA drive current
to drive a single motor.
Specifications:
• Motor speed: Manual adjustable
• Input voltage: 24VAC (+20%/-10%)
• Output: 0% to 100% PWM @ 80 Hz
º 13.5VDC, 5mA (max.)
º Max wire length (twisted pair) 100 ft.
• Humidity: 95% non-condensing
• Operating ambient temperature: 32°F - 120° F
• Dimensions (L x W x H): 4.25” x 2.40” x 1.25”

GE TECMate Pro™
Service Tool
The Tecmate Pro™ Service
Tool, MARS stock #08500 is the
latest advance in ECM technology
developed by and for Genteq
Motors. The Tecmate allows the
service technician to analyze a
Genteq ECM motor independently
of the HVAC system in which it is
installed. The Tecmate can test all
the basic settings of a Genteq
ECM motor, and can detect and
isolate motor failures from HVAC
system failures.
Genteq is the leader in ECM
motor technology. ECM motor
applications are a fast growing
segment of the residential
and light commercial HVAC
market. Genteq's advanced
designs in ECM motors are at the
forefront of high efficiency equipment design.
