A series of six parallel-shaft permanent-magnet dc gearmotors offer continuous torque ratings from 30 to 500 in.-lbs. (3.4 to 56.5 N-m). The VWDIR134 gearmotors come with 1/10- or 1/11-hp (74.6- or 67.8-W) 90-V brushed dc motors. The compact, integral gear reducers feature hardened steel helical and spur gearing for efficiency and durability, with ratios ranging from 10:1 to 266:1 and corresponding fixed output speeds from 152 to 6 rpm. The gearmotors feature built-in face mounting, compatible with Von Weise Genesis mounts, and offer an overhung load capability of 300 lbs. (136.4 kg.). For added versatility, the gearmotors also accept the company’s new TightDrive speed control. The TightDrive motor-mounted speed control can be easily user installed on the rear of the VWDIR134 gearmotors and offers up to a 20:1 speed range. The TightDrive’s durable aluminum extruded housing offers NEMA 1 (IP 30) protection and superior heat dissipation. Speed is controlled with a combination on/off switch and speed potentiometer. In addition, three easily accessible adjustable potentiometers provide settings for minimum RPM, maximum RPM, and current limiting. The TightDrive is designed for 115-V, 50/60-Hz operation.
