Our
standard motors are designed to give good performance
and great value.
The big G43-500 motors work
great for applications that require sustained power output of up to 500 Watts
(0.67 horsepower).
The smaller M27-150 motors
have sustained outputs of 150 Watts (0.20 horsepower). They are available with
either a sprocket or pulley.

 |
These motors are ideal for cost-sensitive applications including robots, motorized
scooters, go karts,
and electric bicycles.
We stock two different standard motors or we can design
custom brushed or brushless motors. See our Pancake Motors
page for motors with outputs of 250W to 350W, or our
High-Performance motors page for
higher power.

Sprockets have 11 teeth and are for #25 roller chain.
Pulleys have 19 grooves and are for 3mm-pitch timing belt up to 15mm
wide. * The above specifications are for 24V. The
motors can also be used at 12V or 18V. The RPM is proportional to the voltage so
running at 12V will result in half the no-load RPM that is shown above for 24V.
The lower voltage also reduces the maximum achievable torque by 50%. The motors
have also been tested and used at higher voltages resulting in higher RPM,
torque, and power. Shorter duty-cycles are recommended for higher voltages to
allow the motors time to cool.
Here are our recommendations regarding the selection of a proper
reduction ratio.
Warranty
The motors are warranted to be free from manufacturing defects, and fully
operational when you receive them. AmpFlow gives no other warranty, either expressed or implied.
Warranties are not transferable. In no event shall AmpFlow's liability exceed
the buyer's purchase price, nor shall AmpFlow be liable for any indirect or
consequential damages.
