Mechanical Variable Speed – Options
“TD” Series
Washdown/Severe Duty
STOBER has developed a severe duty protection package for ComTrac drives which significantly improves the drives ability to withstand the effects of outdoor use, exposure to excessively humid or acidic environments, or spray washed with water or caustic fluids.
The ComTrac severe duty package includes corrosion protection for all functional components and housings including:
- Drive Cone
- Motor Clamping
- Motor Slide and rack
- Bearing housing
- Main housing cover
To prevent corrosion, these components are protected by a special heat treatment process similar to chrome plating. Contact a STOBER Representative for further details.
Electric Remote Control Unit (ERC)
The STOBER Electric Remote Control (ERC) is a compact double reduction gearmotor which is pinon mounted to the motor slide track in place of the handwheel. A mechanical clutch within the unit indicates the end of vertical motor travel in both directions by making a clicking noise.
The ERC can be operated by push button or other type of control (not included). In many applications it is advisable to use a limit switch with the ERC to prevent overspeed or underspeed conditions.
Features:
- Speed changes can be made when the unit is stationary or running.
- STOBER ERC can be quickly and easily added to existing ComTrac drives without using special tools.
- All STOBER ERC units are designed for washdown/severe duty applications and are available from stock.
- Available Voltages include 115V, Single Phase, 60Hz & 230,460V three-phase, 60Hz
