Adjustable Motor Bases

Sliding and Tilting Bases
    It is necessary to change the distance between the motor and driven shaft in order to change speed with an adjustable center drive. The best way to do this is with an adjustable motor base. Lovejoy offers four basic types of motor bases to satisfy requirements of space, convenience, interchangeability, motor frame size, and economy.
Sliding “SMB” Type

Models: SMB143, SMB184, and SMB254
    SMB motor bases are extremely low profile and made of strong, lightweight steel, plated for protection against rust and corrosion. A folding knurled adjusting handle replaces the common round hand wheel to offer easy speed adjustment with minimum effort and no tools. Adjustable maximum and minimum speed stops are included. The adjusting handle is easily removed for the addition of a sprocket or universal joint to adapt to existing control methods.
    For remote control in hazardous or inconvenient locations, Lovejoy offers electric servo motor controlled bases in the SMB style, both chain-driven (MRC) and direct coupled (ERC). Both types come complete with motor, control, and wiring diagram.
