QUALITY MASHIMA MOTORS High quality 12 volt, double shaft Mashima motors are the choice of performance oriented modelers for their repowering needs. Mashima Can Motors offer an excellent fit in most locomotives with two sizes available. The 5 pole, skewed armature is the key to smooth, quiet, low speed operation (as low as 2 scale mph) as well as increased torque and power. Low current draw allows multiple unit operation without overloading most power packs as well as excellent compatibility with advanced command control systems. Choose a matching flywheel set from A-Line's comprehensive assortment of Precision Machined Brass Flywheels. The shorter body #40322 motor is also excellent for repowering many HO scale steam locomotives. For more specs click on the link below.
