For the HP versions, we recommend our VNH5019-based motor drivers (available as single and dual carriers), though these can also be a good choice for the lower-power motors. For the LP and MP versions, we recommend our TB9051FTG-based drivers, for which we have a basic single carrier, a dual-channel shield for Arduino, and a dual-channel expansion board for Raspberry Pi. ![]() We have a number of motor drivers and motor controllers that work with these 25D mm metal gearmotors.

You can use our custom-designed 25D mm metal gearmotor bracket (shown in the picture below) to mount the gearmotor to your project via these mounting holes and the screws that come with the bracket. The face plate has two mounting holes threaded for M3 screws. We recommend screwing no further than 2 mm (0.08″) into the screw hole. Warning: Do not screw too far into the mounting holes as the screws can hit the gears. This diagram is also available as a downloadable PDF (223k pdf).ĭimensions of the Pololu 25D mm metal gearmotors. ![]() The diagram below shows the dimensions of the 25D mm line of gearmotors (units are mm over ). In general, these kinds of motors can run at voltages above and below their nominal voltages lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor.Įxact gear ratio: ``(22×22×22×22×24) / (12×10×10×10×10) ~~ bb(46.85:1)`` Dimensions Stalls can also result in rapid (potentially on the order of a second) thermal damage to the motor windings and brushes, especially for the versions that use high-power (HP) motors a general recommendation for brushed DC motor operation is 25% or less of the stall current. For these gearboxes, the recommended upper limit for instantaneous torque is 200 oz-in (15 kg-cm) we strongly advise keeping applied loads well under this limit. Past purchases have included beds and a vein finder, Smith said. “This one is going to be a huge one,” she said.Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. goes May 4-7, and the typical $1,000 proceeds from the auxiliary’s annual tag day, on May 19, will go to the cause, she said.įundraising totals vary from year to year, but the auxiliary typically raises enough to pay for several pieces of equipment for the hospital annually, Newton said. A cookie day is planned at Petrolia Street Bakery, an online auction via VanKlaveren Auctions Inc. The $20,000 Project Thumper campaign to fund the device hit the halfway point Friday with a $4,000 donation from the CEEH Foundation, auxiliary president Joy Smith said.Ībout $5,000 from the auxiliary, from past fundraisers, got the ball rolling and a Valentine’s chocolate sale added $600, she said. The unit was demonstrated to hospital staff Friday, he said. “The feedback was great. The unit destined for CEEH was being inspected in Sarnia and likely will be available for use at Bluewater Health’s Petrolia site within a week, he said.
